buying an 85 xj 4 cylinder

[bigsliks]

just want to know.

how will I know if the axles are 4.10s?

and they should fit in my 91 without any trouble?

thanks

All 4cyl xj's came with 4.10's... I think...

Wrong. The only way to tell is to check the tag on the differential and if that is gone, to pull the cover and count the teeth.

 

[Chero-King]

Really? oh well, learned something new.

shoot I haven't bought it yet, and I don't want to open the diff, were is the tag normaly?
maybe I can jack it up and spin the tires?

and also it is a standard if that makes a diffrence

id give it a 99% chance of having 4.10s if its stick. ive got one in my garage, and every other one ive seen had 4.10s.

From what I've read your probably right about having 4.10's

the front is a D30 and the back is a D35 right???

I'm not 100% sure.

thanks

I have an '84 4cyl auto, that has 3.73s. D30 front, non C-clip 35 in rear.

Just a my .02 most of those D30 axles had cv axle shafts. Unless it is a disco but I don't think they had the disco till late 86-87. If you run that 91 hard you need to find some new shafts.

I had an 84 4 cyl XJ long ago...It had 3.73...Manual trans....It's not 100% 4.10's.

it does have disconnects, so does this make the axle stronger then the CV style shafts?

I think I will go and jack it up and spin the tires to see what gearing is in it.

thanks guys

I got some axles from an 86 with a 2.5, geared 3.55 with the AX-4 4 speed.
