Thanks!

Dana 30 for sure.

Out of a Grand Cherokee, would be a low pinion 30.

gear ratio is the most important thing. either it needs to match your rear axle, or it needs to be a better ratio and you plan to upgrade the rear also.

For as plentiful as XJ D30's are you might as well wait to find one thats right.

 

If the gears don't match your rear, or it doesn't have gears that are worth making your rear match, and that its low pinion, I would say its probably not worth picking up.

 

it could have 3.55 or 3.73 in that housing, 3.55 is the most common in XJs, so it might match your rear.

 

If it has 3.73, then you would need to regear your rear to match it(probably using ZJ d35 gears).

I talked to this guy and it has 3.55s but it also has a million miles on it. I was gonna pick it up seeing as how it is so cheap but he was 2 hours away.

I have an 86' 2wd Comanche Custom I think ...... Could it have 4.10s? It feels like it launches pretty good.

 

Whats the most common ratio? or how do I determine the ratio, I'll take some pics of the rear axle in the comanche and post'm tomorrow.

What engine? (4 cylinder or V6, count number of spark plug wires if not sure)

 

Automatic transmission or stick. If stick, 4 speed or 5 speed?

 

You could always try to read the tag attached to the rear axle, or pull the cover and count teeth, or see what numbers are stamped into the outer edge of the ring gear.
