Anybody know a source for replacement heim joints that have dust boots and grease fittings?

I have the Petitt solid trailing arms that have worn quite a bit.

 

check Baker Precision http://www.bakerprecision.com/rodacc.htm

or get a set of these http://www.rx7.com/store/rx7/fdlaunchkit.html

 

rotary extreme makes a good set. check them out or use the search button for more info.

if you look up trailing arms they claim the joint is "self lubricating"...hmmmm

at least they have seals

 

You can replace the rod ends with QA-1 XMR-10 (or XML-10, depending on the thread direction) from Jeg's for ~$20 each. I replaced the rod ends in my M2 toe links with these rod ends and they seem to be working fine. The Pettit arms probably use the same 5/8" size rod ends, but it would be worth checking the size before ordering. I chose the QA-1 units after looking at a lot of price lists and data sheets. The QA-1 rod ends are strong and cheap, and they seem to be holding up fine on my car, though I think any rod end is going to be a wear item that needs periodic replacement.

I posted about some dust sealing options from Baker Precision here:

What are some signs of failing Trailing Arms? I have the K2RD Trailing Arms, and theyve been on the car for a while.

 

rear end clunk, unpredictable/inaccurate turn in, rear end shimmy.

 

Thanks all.
