Rear diff rebuild cost

So I need some help from everyone. I have a 1995 with dana 35 rear w/detroit trutrac, 4.11 gears, and upgraded superior axle shafts. The rear end blew recently (the detroit trutrac and ring/pinon need to be replaced, at least that is what is visibly damaged).

Option 1) I have a new detroit trutrac; I just got quoted $1500 to completely rebuild the dana 35 with a 2 year warranty

Option 2) I have a dana 44 (unknown donor) with 3.91 gears. I got quoted $2300 to do the axle swap and put 4.11 gears and detroit trutrac into the d44, most likely a bit more to get the axle up to spec (any mods, brakes etc)

I only plan to do some light off roading, nothing too crazy. What should I do here? Do those prices seem reasonable?

If you broke it once now is the time to upgrade it will cost you less in the long run

Explorer 8.8 at Pick & Pay with 4:10 gears. $150.00-$300.00.
Adapter kit $175.00
E-Brake kit from East Coast Gear ??? (can't be too expensive....give them a call)

If you're lucky, you might even find an 8.8 with LSD.

If you have a welder, it's a relatively easy swap. You'll be into the job for less than half of the lesser of the quotes and have a sturdier axle.

Good Luck, L.M.

What were you doing when it broke?

Option 1 is priced reasonably for what you’re getting, but most wouldn’t spend that much on the D35. If you do, you might as well get a full Detroit Locker for not much more. Around here (West Coast), 4:11 D35’s go for about $200-300.

Option 2 seems very expensive unless they’re having to narrow and provide custom shafts. They’re the doing the same as Option 1, plus welding on spring pads and shock mounts. And you’re right, brakes will be a few hundred also.

8.8 is a great option if you can find a 4:10, but you’re going to pay that shop a lot to do it.

I’d say find a used D35 from a 4-cylinder if you’ll be doing light off-roaring. Leave it open and throw a locker in the front.

Or do the 8.8 but research actual costs to make that swap.

I would be on the 8.8 train. I picked one up cheap w/ lsd just in case I get lucky and break one of my 35s.

Take measurements of the wheel mounting surface and compare the d35 to d44. I think the d44 you have pictures of on your other posts might be to narrow. I think you should look for a 8.8 like recommend above.
