Back to 2010,i was living in Calgary,hanged out with CJA guys almost every weekend,well CJA guys are really nice guys.
I decided to regear to more lower ratio one day,then did a lot research in order to find a good shop local can do this job.Finally with the help of friends on website and CJA,XXXDA PRECISION became my choice.
Got a quote of $2200 in total includ Yukon gears and labor,well the price is not cheap but still acceptble back to 2010 when lots Vendors price over 500bucks one set yukon.
After 4 days wait,the job is finally done,and handed over me a bill of $2600,the guy said they used better oil (WTF! I konw!) Anyway,i paid off the bill and drove the jeep home that day.
One month later i moved back to vancouver,then i heard the hum sound from rear diff on the hwy,but there is no chance for me to drive back let xxxda fix it,cz im 1000km away.
Been 2 years the jeep is just my weekend worrior,only put 10k kms on it,and last week when i opened the diff trying to re wire the ARB ,i found this from the front.
I jus thoght i may playing a lil hard on d30 till i took the jeep to a professional local gear shop.A Really nice guy named Enrico who run the shop i have to say,he found and showed me the reason why my ring and pinion fail.
1 NEGATIVE preload on gear
2 ZERO preload on arb carrier.
3 the pattern on ring is shit.
4 Used the wrong crush sleeve
I was like holyxxck!!!With Enrico's suggestion,we opened the rear diff to check the gear up,and right on,the rear had the exactely problem except the teeth not broken yet,ive been told the xxnda just reused factory shims directly put on without any adjustment!
Now i broke!
All i have to say,XHANDA,YOU SCREWED ME UP!
