When I purchased my 04 Wagon pretty much every suspension bushing in the front end was smoked. I went through and replaced both upper and lower control arms on both sides with Moog replacements. Now I've had another lower control arm bushing failure after only 30k miles. When I installed the replacement arms everything was torqued with the suspension compressed to avoid the usual twisting failure of the bushings. The latest failure the bushing extruded out both sides of the arm. I've never seen a bushing fail like this. Any ideas what caused it? Is this a normal failure for these?
