Steering rack sliding, what to use to scuff bushings?


  • Steering rack sliding, what to use to scuff bushings?

    I was having a lot of steering slop found out my rack is moving all over the place it's a new rack and new poly bushings so doing some research I found instructions from Gary saying about cleaning them with acetone then scuff them with included pad I don't think that was done when it was installed so what kind of pad do I need to buy to scuff them?

    Also the rack and bushings were installed when the motor was out is it possible to remove the bushings while the car is jacked up on stands? I figure if its possible to do on stands I can manage and pull them clean them scuff them and window weld them like Gary's instructions mentioned. I don't have much money on hand to pay a garage to do this and I don't trust them to do it right anyways.

    any feedback or suggestions/tips.
    The saing goes you save the best for last which is why the letter Z was chosen as the last letter of the alphabet. It is also why it was chosen to represent the best car of the 80's.

    Respect the Z

    I had the same problem for a while. I used this sort of pad: http://www.amazon.com/3M-Scotch-Brit…/dp/B00978XCOW
    Worked just fine, you can look at the finish on the bushing and tell when it's good to go. You see all of the gloss go away, and it drags a bit when you run your fingers over it.

    You can do the bushings with jack stands no problem. Just unbolt the brackets that clamp down the bushings and wiggle the bushings out.

    a little bit of polyurethane adhesive smeared over the bushing isn't a bad idea either. it's not like it's going to glue it there permanently and racks or bushings dont need to be changed that often.

    What's poleyurethane adhesive and where do you get it? Better to use than the 3m window weld?

    any hardware store has it. 3m windoweld is a urethane type adhesive. should work the same.

    Gary has a long winded reply to one of his threads regarding the poly rack bushings

    How to clean, what products to use etc

    This thread has a link to how to do it

    Yeah those are the instructions I was looking at, I was just thrown off when it didn't say what material the scrubbing pad was

    I have a solution for this. Was going to manufacture little kits that Z31'ers tend to like but I'm busy/tired and this isn't especially hard or expensive to do (

    you could even weld those tubular ones to the crossmember since theres no bracket to mount them to, or drill and tap two holes and make a bracket with shallow bolts to thread into those things.
    not a bad solution, gary. i might use this!

    I noticed on most new cars swaybars have stopper rings so they don't move laterally, but it's not something you see in steering racks that often… of course most german cars directly bolt the rack to the chassis, so I don't understand the hesitation someone has for going solid mount
