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...

[old_man]

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.

[bigsliks]

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

[jayuu]

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.

[bigsliks]

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.
