My name is Earl, and I have a Stainless Steel bolt fetish =)

Yesterday proved to be a successful day at the shop. (for how little time the girlfriend let me stay there)
I got the rear half of the driveshaft off and started to drop the subframe. I took an hour working from side to side, pounding the subframe down with a hammer and woodblock. The bushing sleeves weren't stuck, but the subframe was at a slight angle so they didn't want to just slide down=) All of that work provided me with this:
I then removed the diff, trailing arms, and brakes from the subframe. That took a while, since I couldn't figure out how to keep the diff from turning while I removed the axle bolts.
I also tried removing the axle from the hub, but couldn't get a socket to sit on the nut far enough. I found out after I got home that there is a locking plate that goes around the nut......I felt stupid, but will be removing it today.
The diff was definitely leaking. Hopefully it is okay. That will get cleaned up today, as well as many other things=)

Very nice progress!
What was your method for removing the diff mount.
Did you mark the front half of the driveshaft in relation to the rear before separating them so that it will still be balanced when reassembling it?
I did not......hopefully I'll be okay.
I just pushed the bushing out by hand. lol It seperated from the metal sleeve. You can still see the steel sleeve in there. I tried hammering it out with a chisel with no luck=(
Edit: I just remembered that PO replaced the guibo. He would have had to remove the front half to do so. Hopefully his marks are still there. I never had any vibration issues. How much does it cost to get rebalanced?

Id recommend finding the balancing alignment marks (painted dots, sometimes a sticker with arrows on a reman. shaft) sooner than later. There may be grease, scrapes, or some other clue that will help you line them back up/make your own balancing marks now before the driveshaft gets moved around/wiped down etc. just in case the factory balancing marks are gone.

I removed the front Sunday I believe. Put it on the ground, picked it up, and set it over by my transmission. I did the same thing with the rear yesterday. So I know I didn't wipe it off if it is there=) I will look. I reckon getting it rebalanced is costly ?
Edit: I felt so proud of myself removing all of this all alone. Now you make me feel stupid=P By the way, do you like being called Snap, or by your name? Your name is Brian (sp) right?

Not sure about the cost of rebalancing. I bought my reman driveshaft from a company in IL that is known for doing BMW driveshafts properly (Wholesale Import Parts or something like that). For ~350 IIRC. If you cant see any alignment marks or clues of how it goes back together then, as annoying as it would be, you could keep re-installing until its right
Call me whatever... Brian, whiteboy, snap, lurp, T-Bone (Seinfeld reference)

drive axles mount up any which way. I even swapped sides (left side is now on the right side) to help even out any wear the ball+cage has had from shock loading in the one direction (weird paranoid engineer overthinking type logic). The inverted hex bolts used for the axles like to get greasy threads so make sure they (the threads) are very clean before re-installing them and use blue threadlocker to prevent them from backing themselves out. It happens more than youd think after someone removes/replaces an axle.
-
You're talking about the e-torx bolts right? I was thinking of switching the axles to the opposite sides too=) I will definitely be rebending all new brake lines for the subframe though. There are lots of bubbles at every bend=/ I now need to go through underneath and see if any others need to be done. All of the lines in the bay are being re-ran to put them out of sight=)

Jake and I got the subframe bushing out today. They were in there insanely bad. I pressed the rubber out with a two jaw puller, and then pounded the sleeve out with an air chisel:) We then tried to air chisel the sleeve out if the diff cover. That didn't work very well. Jake ended up trying to cut it in half with a torch. It worked, but he just barely melted a tiny bit if the cover. It's okay. It was in a thick part:P I also got the trailing arm bushings out thanks to Brian (Snap). Not much else got done. There aren't many things I can do besides the bay as I want for the POR-15 to arrive. We will see what Wednesday brings:)
