Was wheeling in a local ex rock quarry. Saw a toyota 4runner lifted on 32s there too flexed out. I told him to follow me up a hill and he did. We got back down it and he went to take his truck out of 4wd. Heard a loud crunch bang pop clunk. Needless to say his cv axle broke and fell out. Just from the little 15 foot tall hill. I had to jack it up, take off his balljoint, and rig his cv axle so he could drive it home. Damn ifs pos
Well I wouldn't hate on Toyotas because of that. We see U-joints in dana 30's break, snap, and simply dry out all the time. The factory U-joints on my 113k mile XJ were so dried out that it would not flex either way. On the otherhand, my Toyota's 168k mile CV's are mint. Things like that just vary on useage or abuse. Perhaps his were abused and were on their way out.
Back in college I had a guy in a wrangler on a trail ride with our club in Rochester, NY and his lower ball joint blew and caused a cluster**** of ****ery and the knuckle went from vertical to horizontal. What a ***** that was to get that repaired and off the trail. I still love wranglers though.
Parts break no matter what kind of rig it is. IFS or solid, they will break, but is a pain in the *** to do trail repairs so I won't judge you there.
