2001 Jeep Grand Cherokee with Quadra Drive. So, my mechanic says I need to replace a cv joint on the jeep. I've been looking on RockAuto.com for parts and I see two things. A CV joint which is $92 and this Half shaft assembly for $43. Question Is this> is that the CV joint on the half shaft assembly? from some articles ive read, it looks like it might save me some labor just to have him yank the whole thing out rather than just tear it apart and put all pieces of the cv joint back together??? Any info or input????
