Hello,

My car has knocking in front when going over bumps, and it turns out a well described here problem with sway bar bushings. They look good, but here is a way to check: stick a pipe or crowbar between sway bar and frame near the bushing and apply some force - mine moved good quarter inch easy and I could even make it knock.

Any suggestions on replacement bushings? I would prefer plastic instead of stock rubber to firm it up. I see some that "will fit comfort suspension" - how do I check what suspension I have?

I already tried 1 1/8 " aftermarket bushings from energy suspension and can tell - they do not fit. One thing the sway bar is a bit bigger than 1 1/8 " (need to work on my measuring skills), but they also are designed to be installed on a flat frame. Mine is not flat under the bushing, I would need to add a plate even if I got the right size.

If nothing better, I got my eyes on "ÜRO PARTS Part # MNC2102AH Sway Bar Bushing" from rockauto. They do not specify what bar diameter they fit but I hope it is the right size.

Will appreciate any suggestions.

Thanks.
Sam.

 

The lower front damper bushes are also a source of 'knocking noise'.

I bought the uro sway bushes and they were fine, pretty cheap and solved my clunk over bumps.

Cheers,

Got mine from Motorcar, Ltd. Solved some, new shocks (mostly for lower bushings -- see Bob's note above), and new upper bushings, fixed most of the rest. Put new stabilizer links in this week; not much change in noise, but smoother ride. Still struggling with a right front clunking over rough roads in under 30* F; suspect driedout body mounts.

 

Finally replaced bushings, easy 20 min or so job. On the picture old bushings next to new one - no much difference in looks, but a lot of knocking noise from old ones.
To make things tighter I cut a strip of plastic and inserted between bushing and bracket.


Also measured bar diameter with digital caliper - came out as 1 1/8...
