Most 4.0 litre Ranger have an 8.8 whether 2 or 4 wd.
The spring pads might be on top of the housing so
a small sum of 15.00 for new ones plus welding if you
want to go there.
I bought a 8.8 from under a 5.0 Mustang plasma'ed
the brackets off,welded on new pads and got new u bolts
and shock mounting plates . With a set of 15x7 10 holes
the wheels fit perfect,with the stock 6.75 I had to use a .250
spacer to get the tires off the leaf springs and it had approx.
3.5 inches outside clearance to the fender lip.
8.8 Rearend w 3.27 posi (used) 100.00
4.10 gear (used) 50.00
Leaf spring pads (new) pair 14.50
Ubolts (new) 4 @ 8.00 32.00
Shock mounting plates ( new) pair 32.00
Welding pads and shock adapters to plates 35.00
Total 263.50
You can probably source a set of 5 lug axles from Currie or
Strange for 250-300 if you look around.Slide the old ones
out and the new ones in,done and riding in an hour.
