Fixing clunking from RSB -- suggestions?

My RSB (Hotchkis) clunks. I have diagnosed the problem as the swaybar moving back and forth laterally (left to right and vice versa). My endlinks are tight, so it is unlikely they are the issue. Any ideas on how to stop the lateral movement?

We fixed Gonzo2186's Hotchkiss RSB yesterday with similar symptoms.

 

Symptom: Clunking while moving.

 

Assessment: Grab the SB and move it up/down and slightly side-to-side in the bushings. It seems the SB bushing holders that came with the GB are slightly over-sized for the bushings. Either that or the bushings have shrunk.

 

Fix:

 

  1. Take them apart, clean and relube everything really well with SuperLube
  2. Attach the top bolt for the bushing holder - slide it so that the bolt is in the bottom of the slot - tighten it down
  3. Use a large flat-blade screwdriver, and push in and up on the bottom of the bushing holder (in order to "squeeze" the bushing)
  4. While holding tension on the holder, tighten the bottom bolt.
  5. Issue resolved

I recently had this problem and went with teflon tape on the RSB as someone recommended.. it has been quiet for 2 months maybe? I was told that it was around $20 for new bushings at autozone. I haven't found it yet.. but I'll certainly replace with new ones come spring.. or if the clunking comes back with a fury :)

It appears the problem on Gonzo's was that the bushing holder/mount allowed the bar to move around inside the bushings - bushings were very loose in their mounts which meant the bar was free to move around. You could literally grab the bar in the middle and hear the clunk as you push-pull-wiggled the bar around in the bushings.

 

Perhaps adding teflon to the outside of the bushing would fill-up the space between the bushing and the holder/mount, and make for a tighter bushing. But, what we did above, at least in the short-term, seemed to have fixed the issue.

If lateral issues are the only concern, then collars will work to alleviate that. It's possible that the bushing holder sizing v-a-v the bushing itself is the issue.

Gonna try to reproduce those with a couple of hose clamps and some heater hose that I have lying around.

 

Why didn't I think of that before?

if that doesn't work, just install a second RSB and zip tie them together :rolleyes:

 

Don't knock it until you try it...
