Axle Questions

I am getting ready to purchase an 8.8 and a hp30 from ecgs and I have a few questions before I pull the trigger.

I have abs, so can I just remove the abs relay fuse and run the 8.8? If so which of the 3 fuses should I remove?

I have a 4.0 with a 5-speed and plan running 33's, should I get 4.10's or go ahead and step up to 4.56's?

Lastly, without any lift will I be able to run the 8.8 without adjustable control arms for a while?

Any other thoughts will be greatly appreciated!

1) I have no idea, don't have ABS.
2) 4.0 5 speed general recommendation is 4.56 for 33's. If you don't see a lot of 70 mph+ interstate, 4.88.
3) Loaded question. With no lift you can't run 33's without fender mods. What are your long term plans? Seeing how they will set the mounts for your lift height and sye configuration, might just want to do it once. Lots of factors there.

I don't have 33's right now but I want to go ahead and get the axles geared correctly. I plan on 2.5" coils, jks body lift, and adjustable arms, but I don't have the coin to do the suspension mods at the same time. I am going to do a sye and drive shaft too. I was hoping that I could run the 8.8 with stock suspension and arms for a couple of weeks to save some more money.

4.56 is ideal for 33" tires. You can simply disable the ABS system by pulling its relays but the ABS light will stay on. No problem, just pull the bulb or remove the LED if your TJ is newer. My '97 TJ did not have an ABS fuse so not sure if yours does or not. Either way, your braking will work normally after the ABS is disabled for the new axles. You can cut the wiring to the ABS sensors that came off the old axles without problem too.

Yeah, I checked and my 97 didn't have fuses either. Thanks for the response.

Are you ever going to go any larger than 33s? If not, I'd rethink spending money on the 8.8. Just my 2cents.

Probably not, but I really don't want to put any money into the d35 to re-gear. I have been going back and forth in my mind deciding exactly what I want to do. I would rather take the $600 it would cost to re-gear the 35 and put that toward the $1500 it will cost for the 8.8.

This is why the 8.8 is worth every penny.

I wasn't thinking about the cost; the 8.8 is a pretty good value in my mind, I'm actually installing one myself right now.

My thoughts were simply the size of the axle. If you're sticking with 33s, you'll be dragging the 8.8 everywhere if you actually wheel. If you don't wheel you have nothing to worry about, but if you do it's something to consider.

one thing I will add, if you are getting it with a locker go with a full case unit, as the stock carriers are a weak link. Also you good for tires over 33's.. many folks run 37's on the stock shafts.

How many broken 8.8 carriers have you seen or even heard of?

I really didn't think about that. How much more clearance is there under a 44 than an 8.8?

A good bit. Blaine from Savvy (Black Magic Brakes on here) calls the 8.8 a pig of an axle for good reason. If 33s were going to be my max tire size, I think I'd either stick with a D35, or try and find a D44.

It probably all depends on your type of wheeling though. I would imagine playing in the rocks would give you the most problems with it (it's where I get hung up the most), so if you don't do much rock crawling you might be OK, but if you do it's something I would think about before jumping into it.

I hadn't factored any of that into my decision making. I am for sure not going to stick with the D35. Maybe I will spend some more time looking for a used TJ D44, or think about possibly going up to 35" tires. Thanks for bringing that to my attention.
