While driving the Z home from work today, on an exit ramp about 30 miles an hour, i hear a loud BANG, both front tires lock up,screeching halt on the pavement, so hard that as a matter of fact the right front tire (during mid turn when it happened) bound foreward and broke my flarette on the bumper. i have Zero left hand turning ability (or it will bind up and stop) and about 1/2 steering wheel turn to the right before it binds up and stops. my drive shaft, cv
's, and wheel bearings, steering compnents are all tight to the feel. so im guessing its got to be a ring/pinion broken teeth problem, or maybe a junk CV shaft? i just did the iron diff/bravada shaft mod about 4 months ago. the problem still occours in 2 and 4 wheel drive, at any speed.

any one have any help for me? im basically without a vehicle until i find a fix

Jack up front spin tires....grinding? gears crunching? Turn off the tunes LOL

Drain diff and inspect oil to see if it looks like a glitter bomb.

Put your old diff back in so you can dirve.

If you don't have your old diff get a couple of used CV's and use the outer stub axles (take cv's apart) so you can drive. The outer shaft holds the bearing together.

Inspect everything......even after you find the problem.


Good luck man

I busted a ring and pinion, and had no problems turning at all. but when the teeth didnít line up it would lock the front end up, had to back up a bit to unlock it and then slowly forward until it would do it again.

When you did the bravada shaft did you remove the outer clip on the shaft? if you didn't it will push the cv shaft about 1/4 '' towards the hub bearing putting pressure on the cv part of the shaft. it will bind up when the suspension drops and can bust a shaft, IIRC Miles is the guy who knows all about this..

A busted cv could cause the steering to bind for sure..

You should also be able to push the bearing cage up in the cv and pop the clip off the shaft then the stub end will be free. Yeah it is a nasty job with grease all over the place but that better then paying a machine shop to do it. I drove for just about a year with just the stub ends in and nuts on.. not a problem at all..
