Rattling steering rack

I have already bought a used rack from the scrap yard.75bucks including tie rods end to end. There was just this slight clearance between the rack and pinion. But still much better than what I have. It seems the clearance is from the worn housing for both my steering sets. No replaceable bushings on the pinion?

I forgot to tell u something doc.

TNX for the exploded view. You have saved me alot of $$ for that one and for labor fees for the mechanic.

I dismantled the rack from the scrap yard. The pinion was a little bit worn but I think it can last another 200K miles in my hands. There was also a very slight clearance on the rack end bushing, I already changed that one. Im planning to do the installation this weekend. For experts with the proper tools, it will not take long. But for me, maybe it will take take the whole day in replacing the steering, maybe I cant even remove the old one. Any tips on doing this job the correct way?

Tnx again, Ill post the outcome of this job later on.

I made the rack replacement today. It wasnt as hard as I thought. But still took me 4 hours. I've had a few problems disassembly though. One long bolt near the adjustment screw was difficult to remove. Forcing the bolt caused the welded nut on the chassis to peel off. The bolt was turning freely without a conternut. No other choice so I painstakingly used a grinder to remove the bolt head and pushed the bolt and nut inside. Now the rack is installed with one vital bolt missing. Will this be a big problem? If the rack was made of steel, I could just have made a little weld spot to keep it in place. After installation I've found that there is also clearance on the shaft connected to the steering wheel itself. Again I need your support for this job. What part usually needs replacement?

I was suspecting that this steering problems were the ones causing vibration on the cars body. After the steering job, the vibration was reduced substantially, there is still a lot of shake remaining. I've done a lot of repairs and checking already. Shocks, suspension bushings, engine support, allignment of front and back, wheel balancing. This body shaking comes at 50 to 60mph and increases when I step on the gas harder. When the gas is released, no shaking. The last thing Im thinking is changing 2 rear tires. They were not perfectly round when seen on the tire balancing machine although the leads placed on them made the reading to be zero. Do you think this is the reason for the shaking? The tires were just a year old and still looks fine. I need some opinion before I change them. After this, I dont know where else to look for solutions to fix this shaking. I hope you can help me on this one too. Tnx in advance.
