Rock and an expensive place - rear axle

My dana 35 is in bad shape. I pulled the inspection cover tonight and found chunks of metal in the diff. I have sua with a 4" lift. since its probably not worth rebuilding a d35, I think I want to go to an 8.8 or 9". I think I should take the opportunity to soa, but then I would probably have to swap springs too. Does anyone know of a good thread on going 8.8 and getting the ride height right?

Thanks,
D

Why not just find a replacement Dana 35 to putt around in the meantime and work on the 8.8 as a long term project?

8.8 will be the ticket. Do a search here on JF and you'll find more than enough info. There is a LOT that goes into SOA. More than the axle swap. Honestly for the yj it really is as simple as cutting off the stock perches and shock mounts, welding on the new ones, slapping it under the rig, and hooking up the brake lines.

As far as ride height goes, the 8.8 will take about 1/2" out of the lift of your ride height which can easily be remedy with a new set of shackles.

Cheers

Wow never thought I would ever see you recommending spending money on a 35!

Where abouts do you live? I have my d35 laying around in the bone pile....if you're not too far its yours!

Cheers

I'm a fan of taking the time to do it right and if a replacement Dana 35 buys time then so be it.

How did the gears look? If there alright I would just run it until it pukes. You could buy the axle you want straight away. Get er ready to drop in. Then when the time comes get the springs you want and have at it!

I see two options for you at this point if saving money and doing a full soa build is outta the question:

1: you can get replacement d35's for 50 bucks, just swap the whole axle and it'll bolt right up.

2: get an 8.8 from a junkyard and put it in sua without changing anything else (no sye) besides still having to re-weld the perches and shock mounts, and regearing it depending on your stock gearing and what you can find

Those are the budget options. If you want to do a soa build then go for it!

91 YJ. 4.0, 4.10's, 33's, 4" springs, 3/4" booms, 1" BL, 1" MML, d30 aussie locker, hand throttle, posi-lock, full cage, bumpers/rocker guards/engine skid, winch.

Thanks for the replies guys. I picked up an 8.8 from the salvage yard (open) with crummy 3.55. The front d30 and ate up (carrier is eaten alive) d35 are 4.11. I like the ride of the 4.11 with 33" TSLs. I will probably go 35" at most in some aggressive situations. I don't have the $$$ to do the xj or ranger 5" stretch. I would like to do a 2" stretch (rear only for the moment) and go SOA. I have the 3.5" fabtech on there now. I'm going to regear and do SYE with a woods cv (but I only want to do it once).

Question is: does RE or OME have a 44" spring with a 23" offset to center pin that I can swap in for SOA with the 8.8 that would put me level with a 3.5" fabtech front?

Just to be curious, why did you pick up an 8.8 with 3.55s when 4.10s are fairly easy to find? I was able to find close to 10 different 8.8s with 4.10 gearing within 150 miles, ranging from $150-300 each.

None

It will cost you at least 1k to make just those gears changes. Why would you want to do that ?

Couldn't find any 8.8 with 4.10 gears in my area for this price. I didn't think it would cost 1k. I've set backlash on d44 and 14 bolts before. I figure its $150 for gears. I'll add a locker of some sort at the same time. Still trying to figure out which I'm going to go with the locker decision. Any idea on springs? I've chopped ranger bastard packs before and I would rather go re or ome if I can for soa.

No, you won't, the 4:10's are more expensive. That's because it is the one more popular with the aftermarket. And Ford made fewer.
I paid 3 for mine, limited slip, 4:10's, and wish I would have gone open, for the lunchbox locker reason. That's ok. I went full case locker, ARB. THE right decision.
Then got a front axle off a '92 Yj with a 4 banger and 4:11 gears for a hundred.

If you're gonna change out the gears, might as well upgrade to the ARB. Its worth the money to install a full carrier locker.

Air locker? I was thinking more along e-locker lines. Less expensive and simpler to install/maintain.
