I have a 94 4runner SR5 4WD and I was in the middle of doing a BJ spacer lift and I hyper extended the inner CV joint. I was wondering if toyota used the tripod type ( aka trunnion) of the ball style joint.

 

The inner joint is a tripod joint. Just remove the axle make sure you still have enough grease in there, re-install the boot (if it's not damaged) with new clamps, then re-install the axle.

 

If the new lift is going to overextend the joint, you may not want to use that ball joint lift, OR, use a drop bracket in conjunction with the lift. Have you already installed manual locking hubs?

 

ya I have manual hubs and a diff drop but when i was pulling down on the spindel i hyper exteneded it my self. So i should just remove the axle and press it back in?

 

If the boot didn't tear, getting the joint re-seated is all you'll need to do.
I had a similar thing happen with Scuba's truck when he and I were attempting to install the bj spacers on his truck (truck RIP)- had to tip the spindle out so the ball joint would clear the UCA and the inner joint on the passenger side became dislodged. A little finesse and the joint went back in to place with no problems and no damage.

 

or if your boots have already separated, you just end up looking at this




yeah, they got replaced anyway

 

and judging by the amount of grease stalagtites and stalagmites... your boots were gone for quite a while.

and oddly... that doesn't look like a tripod joint...

 

haha, oh yeah... that's a combination of original shafts from 91, T-bars torqued, and a failed manual hub that decided it was going to stay locked
