Control arms
 

I plan to replace the control arms soon at 116,000 but not sure what exactly do I replace, just the trapezoidal looking units or are there other parts excluding struts? Also has anyone purchased the Uro units on EBay. They are 1/2 the price of Vertex or Pelican but I assume you get what you pay for.

With your mileage I recommend replacing everything in your suspension. I recently did this on my S with 103,K miles. A failed Uro control arm central bushing is what prompted the project. Pelican refused to warranty the Uro arm despite it being within the 2 year warranty period. Buy TRW parts, they make the parts for Porsche. Labor should be much easier/cheaper in the long run since everything is connected underneath.

I have a good tested Uro control arm available if anyone is game.
