Backlash

Say a regear was 3 years ago and one or both R&P's backlash has been wacked since.. has irreversible damage already occurred, or is it correctable?

Probably not reversible.

Check your contact pattern and condition of gears .. If you do not have any bad wear patterns you may be able to salvage them

Are you saying the backlash was never correct or it has increased since the gears where set up?

How much backlash are we talking anyway?

Are you measuring the backlash or just twisting the yoke back and forth?

Unfortunately I have no experience with gears. I have not pulled the covers to see. I guess it's time to man up and get in there.

There seems to be more to this story than what your mumbling indicates...

Why exactly do you think your backlash is whacked? Can you describe your problem?

If you haven't pulled the cover, how/why do you think the backlash is out of spec?

It sounds like you're just wiggling the pinion yoke which isn't a good indicator (read as don't).

X2 and a good thought, that's probably what triggered the concern. The driveshaft/pinion shaft can be rotated enough to be very concerning to those who don't realize it normally rotates far more than may seem acceptable. Something close to a third of a rotation is what I recall as normal and ok. The presence of a locker can increase that even more.

When coasting to a stop there's a noise.. Like locusts... not that loud. But I hear it. I've been told after market gears make noise. I've been told it's the truetracs.. It hasn't exploded in 3 years, but I have always heard it. 4WD (the installers) couldn't hear it, nor could the dealership, nor my regular mechanic. But trust me. It's there. It never clunks it never vibrates it drives perfect.

Could be just a noisy set of gears since it has been loud since installation. Also could be carrier bearings going south. Is it only when coasting or under power. Mine used to make noise only when engaged....under power and coasting....it would go silent as you lifted off the gas and the gears mesh switched sides to coast then it would whine again. Been that way for 60K miles.

I appreciate the feedback. It's only when coasting (in neutral).

Get a new shop..I've got a set of G2 gears in a Dana 44 that have survived 4 years now behind a V8 turning 35 inch tires. It's not babied and gets driven fairly hard in normal driving, even more so in the dunes. If your installer did a bad job then it doesn't matter what brand you used...
