My 2006 LJ Rubi has 39 K miles. I am noticing control arm bushing have some rubber cracks in them.
How can i test them to know if they are really worn out ?
No wounds on road or off road on rocks while flexing.
Also wanted to get opinions of what bushings should i consider: Polyurethane or stay with the rubber ?
Advantage of polyurethane is much longer lifetime and maybe a firmer ride.
Thanks
Jay
