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

I used to be able to order FK's from Hotpart for members. I can check. They were great rod ends, but they are still rod ends. I never wore a set out, but I had those on the Teal Terror so it didn't see a lot of mileage.

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

Those might just do the trick. I need to get back under my car and install the UMI poly/rotojoint LCA's that I have in the box. I think they will be silent with very minimal (if any) "binding". The PHB scribes an arc so the front poly "could" get a little sticky. I don't think I'll ever really see it. And the rotojoints on the rear will allow the axle to drop into a pothole on one side and still let things rotate and twist. Or that's how I'm looking at it....guess I better get back to work.

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

Rotojoint/rotojoint is an option. You can get a spanner wrench so you can tighten them down to adjust for wear if they start to clunk. I have a rotojoint/rotojoint PHB and it's silent so far (though a Heim/Heim PHB only adds a bit of vibration in most cases, and not clunking like the LCA's). I almost tried rotojoints on both ends of the LCA's. But my wife warned me that it better not clunk and bang and I better not make her hate this car.

Poly/poly will certainly bind. I'd absolutely avoid that one.
