Clunk in steering system
So, I have a ''clunk" noise when I wiggle the steering left and right, when the car is not rolling. I check every components, and every thing is tight (alignment bolt were checked, ball joints, 949 endlinks, etc). I run a depowered rack, and the pinion was NOT welded. Could it be coming from that? Any idea?
Thanks for your help,
Ben

I'm dealing with this as well.
I've noticed that if I wiggle my steering shaft right at the intersection of the telescoping parts of the shaft that I have a decent amount of play and clunking noise.
How does that part look? I haven't swapped mine out yet so I cant say if it was the culprit.

There's a big 40? mm lock nut attached to the 14? mm bolt screwed into the front of the rack near where the intermediate shaft attaches. You loosen that huge lock nut and SLOWLY tighten down the 14mm nut until you steer and there's no noise. This is easier with a helping hand, but not required. Do NOT over-tighten this or you run the risk of steering sticking (IE: wheel doesnt reset to level) while driving. I only had to turn mine a quarter turn before the noise was completely gone.
You can remove the lockwasher and nut assembly completely if you need to, I had to because it was corroded and seized together, but some PB Blaster and a quick tap of the impact and it broke free (use at your own risk), then I put it back on and tightened it back down.
All this does is adjust the steering lash between the intermediate shaft and the rack, the 'clunk' is the super small amount of play it likely has. In the below picture, the adjustable wrench is over the 40mm nut, the circle with the nut inside is iirc one-piece and is what you tighten, then lock down the lock nut. Both parts can be fully removed (I advise together to keep base adjustment) exposing a high strength spring underneath to set lash (it will not go shooting out unless you're careless).

Bigben: I've had 2/3 of the clunks on here. Left-right 'clunk' at a stop is the preload adjuster. Hitting bumps where the column moves is the two bolts under the dash (even with mine CRANKED, I still get some rattles out of the column). No issues with rack mount bolts at least on my cars though.

Props for excellent info, Der_Idiot. I've noticed this same clunk for a while now, and when I didn't find play in the tie rods, decided it wasn't major enough to worry about yet, and went on with life. Now I know to give this a look.
If anyone would be so kind: I'm 40 miles from my tools and jack, so could you tell me how hard it is to access this bolt while the rack is on the car? Can I just get the car in the air, pull the undertray and go?
