My gears were put in 9 months ago by a gear engineer so imo they was put in correct. Everything was going fine for 9 months and I even had the cover off 2 months ago and they looked ok to me.
This is what happened. I was climbing a small snow mount (mall crawling) and i heard a pop and it was all over. I dropped the diff cover and seen 7-10 teeth laying in the bottom. I called the place that installed my gears and he started the emails and calls the next day ( 1-27-14) And I still have not got any answers.
I did send a email today to Nitro and this is what i got back...
Thank you for contacting us. I’m sorry you are experiencing trouble with your gears. This is the first I’ve heard of it. We’ve literally got hundreds of these out there in use and have had no issues with hardening or other QC problems. All of the gears are made in runs and go through all of the computer controlled heat treating, they are also installed into a gear lapping machine which runs them as matched sets. All of these factors bring the defect rate to such a low rate it is hardly measurable (less than 0.01%) I can say however, that installation errors are one of the number one factors that contribute to a failure. For this reason, it is essential for the potentially defective part to be returned for warranty consideration and quality control review. Typically warranty requests are arranged through the dealer you purchased them from.
-Where did you purchase the gears?
-Who did the install? And do you have any setup specs?
At any rate I’d like to help solve this matter for you."
I know for a fact all this stuff they asked for was sent over. So I called northridge and they said that they have called Nitro but the guy who handles this is at KOH. I understand this but where was he last week? Northridge said I should hear something next week. So I email nitro back and told them what NR said and this is what I got back...
"That explains it. The rep that handles Northridge is at KOH. If time is critical I would suggest purchasing another set, and if yours is found to be defective we can issue credit to the purchaser."
I live in Indiana in the country and we have 9"+ of snow and my road drifts really bad and i need 4WD to make it to the highway so i can get to work. I did get sick of waiting and went ahead and ordered new parts Wed. The only good thing is that it happened now and not 1100 miles away at Jeep beach.
