CJ trans torque mount failure what happened?

After the rubicon trip, I found the rubber torque bushing wasted and the metal bar bent where it attaches to the skid plate / cross member. Anyone know what could have caused this? The motor mounts seem to be fine. The trans has been replaced with T-98a, so maybe with the extra gearing & under heavy torque the mount just failed? Has this happened to anyone else?



Oh ya, looking at the picture, the exhaust is just floppingaround & hangging down on top of it right now, but I don't think that was the reason the mount failed.

Re: CJ trans torque mount failure what happened?

That bolt looks a little whimpy to me but then again, it looks like it didn't snap. The bolt on my T-18 is 1/2" diameter. I used donut-shaped rubber engine mounts above and beneath the bolt head, 3 fender washers and a nylon lock washer. Overkill? Maybe but it has held up. I would also check both the motor mounts and the transmission mount. If these fail, it will put a heck of a lot more lateral load on the torque mount.

Did the bolt happen to loosen up a bit and allow the torque arm to start to slap back and forth every time you start and stop? Just asking because I have a problem with mine loosening up all the time.

Re: CJ trans torque mount failure what happened?

Is that the right Torque arm for that T98? The T-18, T-98 Torque should be the same right? is that torque arm 1/4" thick? or is it stamped steel?

Re: CJ trans torque mount failure what happened?

Thats the original arm that came on the dana 300 when I had the original T-176. I'm not sure how thick it is, but it bent over pretty good. I guess I could make a thicker one and put some beefer bushings in there? Like I said, I have no idea why it got so bent up... the trans even came up and dented the tunnel. It still drives ok, but feels a little sloppy. I guess I will take it into a muffler shop for the exhaust and then look at that mount this weekend. [img]images/graemlins/confused.gif[/img]
