Couple of questions about suspension, clutch, ps lines (long)

[Mike]

Hey everyone, I've been away for about a month or so - long enough for my e34 to develop a multitude of problems:

1. steering wheel wobble: above 30mph or so, there is a distinct sweet spot in the steering wheel, a tiny bit off center where the wheel starts to wobble: During the wobble I hear a very faint vibration sound from driver's side suspension. This happens during speeds of >30mph, but does not go away at 60 or 70. I have pushed the car well over 100 and felt the steering wheel wobble, but like I said before, only in the sweet spot, not dead on straight. Could this be something other than thrustarm bushings? Is there anything I should try tightening first?

2. clutch makes a "rusty hinge" squeal noise when depressed after the car warms up:

a. I replaced the slave cylinder as that is where the sound seems to originate. My hypothesis is that whatever the slave cylinder pushes on inside the bell housing is making that noise - what do you think? Should I try spraying some type of lubricant into the slave cylinder opening in the transmission housing, or would that be a no-no?

b. I really, really do not want to do a clutch job as It catches very well, does not slip or stink. If I have to I will, however. What parts will I need to rebuild the clutch, where's the best place to get them (BMA?) and how much is this going to cost (DIY)? Is it possible to do this job without a lift? I cannot find a procedure out there, it would be very helpful if someone could walk me through the basics, or point me to the right place.

C. PS lines replacement: ps lines that attach to the reservoir developed hideous leaks. Not sure how to get to them, V8 gets in the way . Any tips from V8 owners?

For those who got through all of this, thank you so much for reading. I truly appreciate any answers, you guys are my last hope before my e34 goes and sees a mechanic...

tire or a bent wheel, possibly even bad wheel bearings. I would raise the front end and check the wheel bearings for play, then spin the wheel and watch it for runout to see if its bent, then do the same for the tire, spin the wheel and run your hand along the outside of the tire and feel for ridges or bulges...

2. The clutch ball that the throwout arm pivots on is probably dry and you can't really get to it to spray anything in there...Another thing you could do is to unbolt the slave cylinder and put a dab of grease in where the pushrod contacts the clutch arm..

3. power steering lines are always fun..
