Just bought a 30/35 combo with 4.10. What am I in for?
I just found a pair of TJ Dana Axles (30/35) with 4.10 gears for $100. I had to jump on them (I have the 3.07s). I am very excited about these - I can't wait to feel the difference with my 31s!
How difficult of an install is this? I installed my lift kit myself, but I've never messed around with axles. These axles are complete, though the brakes aren't great so I'm going to use the brakes from my current axles. Is there a good write-up for this?
Personally I don't see this as a difficult install. Use a lot of PB blaster if you are dealing with rust. An impact gun will help save your body too, other wise a breaker bar will work for you.
The front end will be more complicated in the matter of adjusting the toe in and caster. There is a good alignment thread on here somewhere.
You should enjoy the 4.10's.
Cool, thanks - I just read a write-up for the rear axle. It sounds like it's as easy as disconnecting the drivetrain, control arms, sway bar links, trackbar, lower shocks, diff. breathing tube, and brake lines and then dropping the axle.
I also screwed up installing my OME springs (swapped passenger/drivers side front AND rear) so this will be a good opportunity to fix that - plus I shouldn't have to use spring compressors if I've dropped the entire axle, right???
They're not the lightest things in the world, but not unreasonably heavy...I wouldn't want to be under one when it decided to fall on me, though.
To the OP: it's an easy swap...just take your time and study on it. Disconnect anything that connects it to the frame/driveline, and you're done with removal. Since it's the same thing going back in, you'll have an easy time of it. Just turning wrenches, is all. Technically, no more difficult than changing spark plugs...although somewhat more time consuming. Sell those stock axles and make a couple dollars back, and you'll have re-geared for less than $100! Or, even better...keep them for spare parts.
If it's worth doing, then it's worth [I]over[/I]doing.
