Panic fade - good.

First you remove the strut (and cap). If I'm picturing it correctly, then you need a spring compressor to compress the springs so that you can replace the strut cap. Once compressed, remove the nut on the strut which holds the strut cap on. Replace the cap. Most caps have some type of insulator (paper/nylon) between the cap and the spring. You want to use this to prevent noise. Then remount the whole assembly.

I have a spring compressor and lift if you need help.

Now that the panic has faded and I've had a chance to look back at Bently's, here's what I did.
Yes, the strut bolts into the upper strut mount. The upper strut mount bolts with to the body with three bolts. I twisted off one of those bolts on the passenger side upper strut mount. I should be able to replace just the bolt. But I think I have to remove the whole strut assy just to get to that bolt.
I'm thinking this is all related to the front end problems I've noticed. Something was weird with this strut. Why did it twist off at about 18 ft-lbs? If the torque spec is 16 it should have withstood much more than 18. Also I found that according to Bently's that I have the 1989-1992 type struts in front. However, my car is a 1995 with only 48K on it. I'm not sure what all of this means yet, but I beginning to wonder if I'm just starting to uncover what may be many more problems.

Chris,

Not sure on your car, but doesn't the strut bolt into a cap with one bolt and the cap mount to the body with three bolts? If so, you should just be able to replace the cap.

Should be safe to drive, but I wouldn't go racing with it that way! If you want, call me next week and we can work on it some evening.

A '95 525iT.
I was checking torque on the strut bolts that bolt the strut into the body. There are three on each strut under the hood. Some were torqued to about 10 ft-lbs. Others to around 15 ft-lbs. I realize the spec is 16 ft-lbs. But I thought I'd torque them all to 20 ft-lbs because I've been having some movement under the front end that I can't figure out. Anyway I went around to torque them all to 20 but one of them only went to about 18 and then twisted off.
Is the car safe to drive now? Should I go with an OEM single strut or replace both with an after market?
