Hey All,

A quick follow-up...

I was incorrect: my 01 XJ 5sp manual does indeed come with a Mopar 8.25"
rear differential, and the gear ratios are 3.07:1. Yikes, no wonder I'm
having problems with the 30" tires!

Anyway, I've pretty much decided to lower that ratio to 3.73 and to
upgrade my rear Traclok to an Auburn limited-slip system. (Based on Bill's
post, the chart on ratios seems to indicate that 3.73 will still yield a
lower ratio than came stock, and I was happy with that for my
application.)

Regardless, all of this still leaves me with still more questions:

(1) I drive mostly highway mountain (my house is at 7500ft, with town
around 5000) miles, and have 4wd to deal primarily with ice and snow
conditions on these roads. Should I consider moving from an open front
diff to a limited slip? What are some of the things I should consider in
making that decision?

(2) Finally, is, in the opinion of your esteemed group, 3.73 low enough,
or should I consider going with a 4.10?

many thanks again,
john

Wouldn't that be a "higher ratio", which of course yields a lower gear?
(hear we go again :-)

Does it go good enough now? Do you intend to do any off-road? A lLocked or
limited slip front can cause handling/steering issues in snow and ice.

Do you ever intend to go bigger than 30" tires? If not 3.73 with the 4.0
would be fine.

I've had no complaints thus far, but I've never had it stuck either (I'm
pretty conservative). I guess what I was asking is whether or not going
limited slip would make my set-up more bullet-proof.

I do take it off-road, but only as a means to get somewhere; I am not
going to make this vehicle a rock crawler. Your last statement gets at the
crux of the matter: I know that a locker will affect handling in slick
conditions; I didn't know if that was the case for limited-slip.

I cannot imagine going to bigger tires.

Thanks for all of your advice; it's really been helpful.
