It was the rear ring & pinion on a Dana 44 and the pinion gear was chewed up just like the ring gear.

 

Thanks man

 

Sounds like your gears were never set up properly then.

 

I did this to RubyDoo at Ocean Shores, WA. and the R&P are fine.....

 

Man that Sucks I hope both my JKs dont do this one day!

 

There's a 500 mile break in period when you get new gears where they say you should not go over 65mph, do any hard accelerating, etc in order to allow a nice wear pattern to occur on the gears. Were you able to perform this? If so, maybe switching to a different brand such as Yukon would help (I have theirs in 5.13 as well with 40" tires). Though I've seen quite a few Superior 5.13 gears being ran on rigs with Dana 44s and 40" tires without any problems....and they wheel them hard.

 

still never answered how many miles did each last? I'd be going to a different shop thats for sure and I hope superior warranties them but I understand if they dont.

 

I would think the 37" tires might have something to do with it.

 

First set of gears lasted about 10 months then they broke the second set lasted about 5 weeks and I am pretty sure they weren't installed correctly. I am waiting to hear back from Superior Gear about warranty claim if possible.

 

Well there are several people I know that are running larger tires than 37" with the same gear set up and haven't had a single problem. So I don't think the tires are the main issue probably the mechanic who installed them.
