I am looking to swap in an 8.8" as part of my LT1 project. I was wondering if there were any common problems that occur? I have read that the rear is slightly narrower and was wondering about the alignment? It has 4.10" gears and disc brakes so I wont have to change the gears. I was also wondering about the master cylinder if it had to be changed? Thanks.

as long as you are useing aftermarket wheels you should be fine and as for the master cly i just used the stock jeep one and had no trouble

why do you say aftermarket wheels? Ths bolt pattern is the same, is it the depth of the wheels?

I also had another question a little off topic. Which Dana 44 front axles are most people running/out of which vehicles? Looking for the best match for my 8.8, thanks.

as long as the wheels have less backspacing then stock

the d35 pumpkin is offset a little bit did you have any problems with that

no i had mine set up with 3.5 lift springs and i used the stock drive shaft and all

did you have any problems getting it aligned?

no i used the m.o.r.e. 8.8 kit and i had no problems it drove fine on the street

ok this looks like a good kit ill prob use it for the rear, which wheels did you use? Did you use any lockers or anything? Any other tips for the swap?

i ran steel 15/8 steel wheels from jegs i ran 38/12.5/15 tsl no locker stock lim slip with 4.10s

what kind of back spacing?

i want to say 4" but not shore

8.8 is a great swap, yuo gunna be happy

There's nothing on a YJ that is going to affect your alignment. As long as you weld on the spring perches straight you'll be fine. The 8.8's pumpkin is a bit more offset but nothing that will affect your drive line angles.

The stock wheels are about 5.5" of backspacing so the 1/2" narrower for the 8.8 might give you problems.

I do know a guy that has a TJ front 44 with no brackets on it (including the upper control arm). I know he wants to sell it, but don't know if it'd be worth it to have it shipped from AZ to WV.

Well i know you cant align the front but i was wondering with the narrower axle if the machines could read. I was thinking about get longer wheel studs and spacers. I wanna run 33"s should I get 15x8 istead of 15x10? Cause it looks like the backspacing would work.

Considering that the 8.8 is only a rear axle and you have leaf springs there is absolutely not alignment that can be done in the rear.

Honestly it's only a 1/4" on each side so don't worry about the width of the axle. If you get wheels with 3.75" of backspacing you won't even notice the different. It's actually good for the front to be a tad wider than the rear. Helps the rig track better.

understandable, the reason why I asked about the wheels is because he mentioned he ran 15x8 w/ 38"s. I wanted to run 33/12.50 and I thought 12.5 and wider you were supposed to have 10"wide wheels is this not true?

check this link out:
Ford 8.8 Axle in YJ

so that the 8.8 is disc and not drum will the master cylinder or any lines have to be changed in the yj? i am thinking of doing this swap and oh yeah would you have to match the spline count

stock MC is working fine for me with 8.8 discs.

Match what spline count? The 8.8 is an easy almost bolt in swap. There are no alignment issues when usingf it and the backspacing can be the standard jeep backspacing with no ill effects.

Your master cylinder should be fine with discs or drums as that m/c pushes about the same amount of fluid as the ford m/c. You will have to plumb in the lines and if using discs you will have to get two rubber lines for the ends at the calipers.

You can get spacers if you want to even out the wms but it is not necessary as most vehicles are already smaller on the back axle for tracking purposes anyway.

Most dana 44's will have a different wheel pattern but I think one from a waggy will work. Do a google search or go to Naxja, I know I have seen it on thier forums several times.

I am getting the axle tomarrow. Now my only worry left is getting vibes from the offset driveshaft. Anyone get these and how bad?

Most axles are offset from the factory, there is no need to wory about the vibes i doubt you will have them from the offset.

hopefully I dont get any. I appreciate everyones help. I was gonna do the shock extensions as mentioned in the link should I just run the factory shock length? And I was wonder what shock would be good for the front w/soa.

Would I cause any problems by mig welding the axles tubes or brackets?

just a question. full width or narrow? for full do a 14bol full float rear and a dana44 hp front out of late 70's ford.

narrow get the 8.8 and a dana 44 out of a waggy.

what pinionangler are most of you running? I havent seen a number yet so I hope no one is just eyeballing it.

i pointed mine just a hair south of straight at the tcase yoke.
