So I just returned from the Sandhills Open road challenge in Nebraska ...

The roads in Nebraska, including the two race courses, are NOT quite as nice as in Utah.

The rod end clunks / pops / bangs on my rear suspension has now become unbearable, and I would like to "fix" it / shut it up before the SCCC next month

Currently the car has

Alumunim LCA's with rod ends both sides
Aluminum PHR with rod ends both sides

I've always just went full rod end, (same setup on my 3rd gen also), BECAUSE RACECAR ! , But I'm getting older :)

OPINIONS PLEASE ! : (cost IS somewhat of a factor, too many projects!)

1. Replace all the rod ends with new FK's (anyone have part #'s ?)

2. Replace chassis side with Poly ends http://umiperformance.com/catalog/index.ph...products_id=262

3. Go to arms with some sort of "joint" / "ball" / "rotator"

4. Poly ended LCAs

AS an update to this I ended up ordering these:

Poly on chassis end, rod end on axle end ...

and WOW ! WOW ! WOW !

Clunks are almost completely GONE (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) ... the other rod end / rod end arms were just plain worn out (IMG:http://www.frrax.com/rrforum/style_emoticons/default/sad.gif)

Next will be the matching Poly/Rod end panhard rod and car should feel "new" again

P.S. took 3rd place in the 130 mph class at SSCC 129.9772 MPH, 0.4364 seconds late

Just put the roto joint version on it or fresh rod ends (the PHB).

First, climb under the car and shake the phb. Really give it a good shake (or tap it with a dead blow rubber mallet) and see if it clunks. I've run Heim/Heim PHB's for years without anything more than a slight increase in vibration (but nothing objectionable, it was just enough that I could barely put my finger on it). It might just need refreshed.

The rotojoint PHB I'm running has been completely silent. I've not taken it autocrossing, but I've loaded the suspension pretty hard a few times in corners (and two pavement dips on back roads that resulted in landing "flat" on the SFCs, it was just a spot in the road where the pavement sank, but I found them at 55 mph or so). The rotojoints are still silent (and wife approved).

It really has been fun building a car that really handles well that makes no unusual noises....none.
