What causes front right side suspension noise in 126's? sounds like a bumping noise when it goes over minor pavement imperfections?

As I mentioned in the other thread, guide rod mounts. Try doing a search for "guide rod mount". There have been a number of posts about them, including several how to DIY them, some with pictures.

When the mount goes bad you will get a clunking sound coming from the footwell, or footwells if both sides are shot, when going over speed bumps or pot holes, might even happen when stopping in reverse. The guide rod is the support rod that comes off the lower control arm and runs back to the bearing bracket.

usally 3 things,one is the sway bar bushings ,usally the outter ones. Or the lower or upper ball joints.And third wich i think might be your winner is the caster adjusting rod ball joint.On the lower control are there is a rod that goes to the rear (caster adjusting rod) and where it mounts to the body it has a ball joint.Once the boot brakes water gets in and wears it out

I'm with guide rod mounts. Another way to tell is after a stop, when you first let off the brake, you can feel a little give as the mount moves.

I replaced mine last year. About a two hour job the first time, not too bad. Do a search.

Camber adjusting rod and guide rod are the same animal, just different names.

Semantics.

Tie rod ends will as well. Both of mine wore an outer tie rod end and they made a nice clunk going over bumps.

Take the wheels off and pull, push and look. You will find the problem.

Thanks. Did the end rod mounting kits; definitely need a 2 ton press to remove them. while there I changed the back and front big rubber donuts bushings located in the arm (2 ea side; one large; one smaller). Now I got a big rubber squeak from the right side: cause? is it a correct torquing issue? what's ideal torque for the bolts holding those big rubber bushings?

My 85' does not "clunk", but when it is below 45* outside, when I hit a "wavy" bump where both struts are compressed at the same time, it will make a "scrunching" noise. Not a big deal, because most every later model car I have owned in the past has done this. My 90' Lexus did and my mothers 97' Oldsmobile does this.

My older cars do not do it. My 73' Pontiac and 69' Chevrolet have super quiet suspensions.

Thanks for your post. My 89 SE has similar noises. I am in process of finding the front end parts to go after the problem. You've given me a good place to start.
