Solid rack guide update in steering rack needs continual adjustment

Hi Folks

I did the update on the rack guide to the newer solid bush, but it keeps needing to be adjusted all the time. 6 months go by and the rack is moving around again. No wear on the bush or the rack. The only think I can think of is that there is a bearing for the bottom of the pinion shaft that could be collapsing? it feels fine when adjusted with no tight rack or anything. Ceratinly doesn't feel like a bearing going bad, but needs continual adjustment. 3 times now in less than 2 years.
I adjust to 18 ftlbs then back off 19deg.

How would locktite help??

The lock nut is still there - the guide has NOT moved (because I mark it).

How many miles on the rack? I had the Same kind of thing happening on my original rack years ago after doing the rack guide. I had to tighten mine to the point where the wheel was stiff to turn. If I had in any looser the rack felt terribly loose. There was no middle ground. So in the end the solution for me was to replace the rack which had around 180k miles. I then went through two sets of remanufactured racks in a year, both of which were just as crappy as the first rack. Finally I spent the money on a new rack from safari ltd.
 
The solid bushing (assuming steering rack guide) is great for doing what it's supposed to vs the roller guide. It just doesn't happen to be what's going on with yours, perhaps.
If I've got this correct the nut that holds the guide in place is NOT backing off? You just keep tightening it and that seems to solve your rack movement problem for several months? What do you mean by rack movement? The inner tie-rod is all over the place? The pinion imput shaft is moving around? The whole rack is moving around?

Just trying to get a solid idea of what you're describing.


I've done a solid guide to fix the 99's issue and a new r&p to fix the 96's....in both cases my inner tie rods were good....how are yours?

Correct, the guide and/or lock nut are NOT backing off. I'm an engineer so very adept at most mechanical work.
Rack movement - yes I mean the rack shaft itself moving inside the housing, giving the same knocking sensation like the old roller bushing. I can move it by hand when it gets real loose. Then when I retension the bush, the old marks are nowhere near being correct, so I go through the torqueing procedure every time as mentioned above.
Pinion shaft seems to be nice and solid, so I don't think the bearing at its base is bad but of course haven't pulled it out to see.

Tierods/rack ends perfect.

Rack bushings nolathene and perfect.

new r&p to fix the 96's?? what does that mean?

Sorry, had to replace the 96's rack & pinion with a new one to repair my '96's problems, wobbly imput shaft...had the kid turn the steering wheel back and forth while I watched to find that one.
Rack bushings, solid guide, for sure good inner tie rods (?).....in my limited two truck experience you're running out of options beyond the r&p.

Time for me to step back and let people with more knows than me mull on your answers and give you more ideas/info.
 
I have play up and down on the drivers side rack and tie rod inner and outer are both good. The rack shaft moves up and down when one wiggles the drivers wheel. I'm interested to see how this ends up.

I know this is a bit old but I have the same problem on the driver's side. I just got back from Toyota and will get the parts tomorrow. We'll see if it fixes my issue.

Keep us posted. I still haven't done anything. Only notice it when it's up in the air looking for bad balljoints.

You ordered a replacement guide?

Yeah the guide and 3 other parts recommended. I was going to just get a new rack but I figured I'd give this a try and maybe get a few thousand more miles out of it.
