I'm not convinced this guy understands what is involved in gear set-up (no

Re: Differential gear change question
Just buy the 3.73's for the front. Yes, it is more expensive. BUT, if you
screw up the install, the TJ is still driveable, and its an upgrade. Don't do a bunch of extra work for no improvement! Keep the LSD and the 3.73's, upgrade the front gears and be happy.

You must have misunderstood my questions if you think they suggest a lack of ability. Usenet is such a wonderful place to ask questions.

The higher the numerical ratio the thicker the ring gear and therefore the mounting flange on the carrier varies to compensate. > One has to be wary about advice using various terms for parts, words > that differ from the manufacturer's, which are themselves confusing.

All the information you need to set up a differential is in the factory service manual.

Man, I am comfortable tearing an engine down, but I sure leave the gear

The first one I did was a straight replacement when I chipped a tooth and that really suckered me in for the later ones - pinion depth was dead on first try, backlash was right in the center of the range, wear pattern took one shim change to get dead on - man, this is easy! The other times were a mix, but after taking nearly two days to set up the last one I did, I came to the same conclusion you did: pay a pro! I like to never got the pattern right on that one when I was going to a different ratio. -- Will Honea |
