<![CDATA[94 325I E36 Rear shocks leak instantly]]>I have a 94 325i in our shop and we keep replacing the rear shocks because they leak.  We started with KYB (#KG9136) and they lasted for about a year.  The customer has a no leak rule at her condo and was notified of fluid drips in her driveway.  The shocks were under warranty so we replaced them.  A month went by and the right rear was dripping again.  At this time we figured there was an issue and found the rust old coil springs were lowering springs.  KYB tech line said it may be causing them to bottom out on the seal.  I called Billstein and they gave me a number (#24-027250) for their shocks that are made for lowered cars.  Installed the Billsteins test drove and in under 5 miles they both are dripping.  We compared the ride height to a know 1.5 inch drop E36 and are now lost.  Any ideas???  I am now in a bind now because the customer has had our loaner car for over two weeks and i cannot give the car back unrepaired.

If they are overfull, they should not fill them so much at the factory. They obviously aren't using Poka-Yoke

I cannot think of anything that would cause that besides severely worn out springs, causing the shock to bottom out constantly.

Seems like the rusted out springs are the issue. Or has there been any damage to the rear end such that the suspension geometry is off and putting tension on the shocks?
