http://www.yuccaman.com/jeep/gear1.html said:The gear manufacturer also plays a bit part in the strength of the axle; some manufacturers build their junk in China, and quality apparently doesn't translate correctly. Here are a few thoughts on the matter:
- You can keep costs down by installing a locker at the same time as the gears are changed. While the parts are more expensive, you pay for labor only once, and in many cases you won't have to buy a new open carrier that will be removed with the locker anyway.
- You can regear one end at a time if your budget is tight. **HOWEVER** make sure that you remove the front driveshaft if you do this, to prevent severe damage to the drivetrain. (the availability of this option may vary by vehicle)
- Don't use someone else's used gears unless your Jeep is a trail-only rig. I did, and learned the hard (and expensive) way that used gears are a pain to properly set up, and they are 99.99% guaranteed to be noisy.
- Stay away from some of the companies offering lifetime warranties. Genuine Gear is one of these; they offer a no-questions-asked lifetime warranty on their gears, but I've talked to enough installers to keep me away from those. The quality is shady, the gears are known as "GenuWHINE" by many, and a lifetime warranty on broken gears doesn't include the damage that a broken gear can do inside the pumpkin or the labor costs to remove and replace... I've heard the gears recommended in roughly this order; your mileage may vary:
- Spicer
- Superior
- Yukon
- US gear then
- Precision
- Richmond
- Sierra
- Value Gear
- Genuwhine
