Another daily driver thread: E34 525i
-
Input from other e34 owners would be greatly appreciated on this one.
give up now? lol I replaced basically every component in the e34 steering (besides the steering box, itself) and it still wasnt perfect. always chased my tail on that.
tramlining, specifically, is caused by something loose, i.e. worn ball joint or bushing. the wheel is allowed to move out of alignment from the rut in the road, even with the steering wheel held in place. anything in the front suspension with a joint is in question.
also, nice eye! sounds like a great fishing trip.

Tires on backwards by chance? Hard to tell for sure from the picture but that could have an effect on tramlining too
Backwards tire could cause noise or potentially improper or accelerated wear but couldn't cause a wander like he's describing.
I'd suggest taking the tires to someone with a road force balancer and have them straight track the tires. This will diagnose a tire issue if it exists and they'll be able to tell you which position to mount them in to avoid and minimize pull or wandering. If that comes back good then @straight6pwr is most likely correct that it's a loose suspension part. Strut, balljoint, tie rod, etc. You pick and it can cause this concern.

Also, you're probably on the right track with a narrower tire helping. Wider tires are more prone to this phenomenon. I just dealt with a dealer who had a customer that put his first set of 35's on his stock truck and had the issue. They road forced, inspected, etc and eventually went back to the stock size per my recommendation and it fixed it.

Yes, they were mounted backwards (I know, dumb on my part) but I swapped them to the correct direction and it only had an effect on road noise.

Wow that's a great looking walleye!
It definitely was! The one my grandpa caught was about an inch shorter but probably a half pound to a pound heavier, it was an absolute tank. I caught a 22 incher on the last day, never thought I would consider that small haha. Three of the four filets from my dad and grandpas fish fed five adults with leftovers!

Yeah, that’s kinda what I figure it’s going to take to totally get rid of. It’s not horrible by any means, just a little surprising if you haven’t experienced it before or don’t know to expect it. There’s a bit of slop that can be felt in the steering so the first check will be the steering box itself, and I’ll do the adjustment on it. I’ll see if anything is visibly worn or loose and go from there I guess. And yeah, it definitely was! I can’t wait to go back.

I’ll definitely do this when the pilots get mounted, thanks for the advice!

the most likely causes:
if you feel the tramlining/extra vibrations over bumps under heavy braking = upper (thrust) control arm bushings are bad. try stabbing the brakes over some railroad tracks or some bumpy road section and see how bad it feels.
if you only get the tramlining over bumps = pitman arm has play or tie rod ball joints. both are easy to diagnose. jack one front wheel up and try and wiggle it in and out and watch for play. for the pitman arm, if it is worn you can push it up and down.(not side to side)
generally, the adjustment of the steering box only improves the vagueness at the center of steering

Maintenance time!
Finally got around to taking a look at a noise from the motor that has been increasing in volume lately, sounded like a pulley bearing on the way out. Made like a high pitched whine/grinding noise and was worse when the car was cold. Once warmed up, it quieted down reasonably well. Started by removing both tensioner pulleys and the idler pulley, removing the seals, and repacking them with some high temp grease. They were all pretty dry and crusty and that definitely quieted things down, but didn’t completely eliminate the noise. Because the new pulleys are so cheap, I just ordered new ones rather than trying to stretch the life of the ones on the car, just not worth the risk to me.
I then looked at the alternator, which upon inspection had bad bearings (spun like there was no grease in them anymore and were a bit crunchy sounding). Attempted to replace just the bearings but couldn’t get a few fasteners off and just said screw it and bought a reman unit from O’Reillys. Lifetime warranty on the unit, so even if it’s not amazing I’m fine with replacing it every few years for free.
Finally, I have a new set of front sway bar links on the way to address a front end clunk that started a few months ago.
On a different note, I’m ready to begin priming and painting the m-systems after stripping and media blasting all the old paint off. I was told by the seller that they had been previously stripped and painted, but it seemed that only one of the wheels had received that treatment; the other three had what looked to be the OEM paint underneath the rattle can paint. No matter, it was all coming off anyways.
After some discussion and deliberation, I decided against my original plan of polishing out the lips and will instead stick to paint for the whole wheel. With that said, any thoughts on a color for the lip? I can’t decide between a bright, almost “polished aluminum” type paint to give the look of polished wheels, or if I should just stick to the stock OEM BMW silver paint. Stock paint will likely be easier to sell, but I do really like the polished lip look. Any opinions?

Obligatory 2 week after I did the work post:
Replaced front sway bar end links, which solved the main clunking noise in the front end but left a smaller one that is (I think) isolated to the right side. Going to inspect the upper and lower control arms the next time I’m home, I’m thinking the uppers are the likely culprit.
Yuck.
Double yuck. Ended up just cutting the upper nuts off, way easier than grinding up a wrench to get into the tiny little recess to hold them. Speaking of:
Going to put this into the pile of tools I’ll probably never use again, but I can’t bring myself to get rid of.
Much better.
I wasn’t originally thinking this car was going to stick around past this spring, but it’s beginning to look more and more like it will. There’s a few maintenance items I plan to take care of if it does:
- Replace the seals on the VANOS unit and install the anti-rattle kit. I already acquired a spare unit that I’ll rebuild beforehand to make it a quicker, easier job.
- Identify and repair whatever is clunking on the front end. I may just end up doing a full refresh of the bushings and steering, I’m undecided. If I hang onto it, it’ll stick around for another 4-5 years at least so it may just be worth it to do it now and enjoy the better suspension for longer.
- Shifter refresh (sorta finished? Z3 shifter and new bearing cup installed)
- Go through the steering system and replace everything, might as well future proof myself
- Drivers front and rear window regulator replacement
- Cooling system check? It had the water pump and I believe the radiator replaced preventatively by the P.O. but I’m not sure if anything else has been changed.
- Paint the front bumper
- Replace both roundels
- Door brake reinforcement. This will happen regardless of whether the car stays or goes
- Repair headliner
- Swap out the general module under the rear seat with a known working one to see if it solves the cold weather issues with central locking and flashing interior lights
- Replace rear seat belt trim pieces, and fix the front seat belt height adjusters
- New tan floormats to replace the black/red ones it has now
Potential upgrades and projects:
- Lowering springs and upgraded dampers: I’d like to retain as comfortable of a ride as I can while eliminating some of the front wheel gap and giving a slightly sportier ride. Since I’ll likely replace shocks and struts anyways I can do it while I’m in there as well. Any recommendations? I’m leaning towards eibach springs and Koni sports, but am open to suggestions. I’ve heard that the bilstein sports are pretty harsh for a daily driver, and the h&r springs are also on the harsh side. I REALLY wish I could retain OEM ride comfort while taking an inch or two out of the front, but I’m not really sure how that’d be possible.
- Add a limited slip. This’ll be a winter car, so extra traction would be greatly appreciated. Also, rage drifts.
- Add E32 adjustable lumbar supports
- Rear fog lights
- Add the ski bag pass through
- When it comes time to do brakes, upgrade to f30 335i/340i fronts (4-piston aluminum Brembos, 340mm rotor) and buy the spacer kit for it, and swap to e34 540i/M5 rear caliper and rotors. This would require 17’s at minimum which sucks for winter tire options, but big brakes are sweet. It’d be a great excuse to autocross the car some as well.

Are you swapping seats or can you actually get the parts to add lumbar into the e34 seats? Our lists are pretty similar
From what I’ve read, the seats are identical on e32s and e34s down to the mounting slots and harness, so it should just be as simple as bolting the mechanism into the back of the seat and plugging in the motor and switch. My seats are in pretty good shape so I don’t plan on replacing them unless I come across a screaming deal for a full black, blue or red interior to swap out.
Do you remember off the top of your head what springs/shocks are on the 540i/6 that you brought to the last fall meet?
-
my wrench always fit those flats on the sway bar arms. but i know that different brands have different thicknesses.
if you need a modified 22mm (7/8") wrench for the bolts on the upper control arms, let me know Ill ship mine to you.
like your modified tool, after modifying it for the e34 i've never used it again

It fit but was tight for the stock ones, but the replacements were tighter and I didn't feel like risking a tear in the boot. Thank you, depending on the way things go I will let you know!

I had to do some digging but that's the info on E32 seats I have. I never did rewire that seat and it did get scrapped with the car because I couldn't remove it. I still have the passenger seat from the '89 750i if you want to rip that apart or do wiring experiments on. If you break things I have more e34 seats too
The current 540i has BC Racing coil overs. Ben didn't mention what rates he bought in his thread. I haven't gotten around to raising/adjusting them to my liking because they can be harsher. I think h&r/Billy sports is what I'm gonna get for the 530i.

Interesting, I didn’t know that. I’ll definitely take you up on that though, I’d be very interested to see the differences and if a little splicing wouldn’t work. There’s probably some other random e34 parts from your stash that you have that I would buy too.
If you end up with that setup, let me know what you think of it!

Checking thing off the list slowly but surely. The new door brake and door reinforcement plates arrived a few weeks ago and will go on whenever I feel like welding the plate in, both roundels were replaced, driver's front regulator was replaced, general module was replaced, and I put a Z3 shifter in last night. l'm a big fan of the shorter throws and feel, it'll be interesting to see how notchy it feels when it gets cold again though.
Next on the list is rear sway bar links, a few new moulding pieces to replace the ones that are rusting and falling off, and lumbar for the driver's seat. Between all that and a new apartment, I'm going to be busy the next few weeks.
