hey all

it was my lucky day today i picked up a brand new 5,29 diff for a 2,8td for free of my gfs dad.

But now the problem is he was telling me how to install it but he made it sound way hard lmao! so i was wondering if someone can give me a run down on how to do this.

Thanks

Is this the Paj in your sig line ?
You must have the same ratio front & rear, or else when you're in 4WD they will turn at different speeds.

Anyway, to change the rear diff centre.
Jack up the rear, undo the tail shaft, drain the diff oil. There are four bolts on the end of the axle housing that hold the hub on, Undo these and pull on the wheel to slide the axle out. You may need to undo the bolts holding the brake cable to the control arms. Slide both axles out as far as you can (you should be able to tell when it's not in the diff anymore). Undo all the bolts around the diff centre and lift it out.

Do the reverse to install the new one :)

oo okay m8 sounds not to hard.

im guessing im going to have to try getting another diff i was looking at the pajero tech talk and says 4.625, 4.875 does that mean back is 1 and front is other or they are one or the other, and where will i get another 5,29 dif if i need it from and for how much.

thx

The first thing you need to do is double-check the size of the diff centre. The 2.8td should have the 9.5" rear, yours should have a 9" rear - could be an issue... ;)

4wds normally come with the same ratio in both front and rear diffs. All the info you need should be in the Tech Info thread.

Count the number of bolts holding the diff head in.
10 bolt = 9 inch,
12 bolt = 9.5 inch

The front and rear diffs are different sizes, but need to be the same ratio.

In the info DB where it lists two different ratios, One is for an auto & one for manual.

oo ok well mines auto so im guessing the diff i got wont fit because i counted the bolts on my front diff and only has 8 bolts, so must be smaller than a 9" im guessing so then.

what end are you planing on putting this into. it wont fit in the front. do you have leafs or coils in the rear of it? if its coils i think it will fit in the rear but if its leafs you wont be able to fit it.

either way, dont fit it till you find one to match for the front. i have one here but im in NZ.

Your new diff, rotate the pinion and count how many turns you do until the axle (at the end) does a complete turn. Roughly 5 and a quarter is 5.29 and so on.

And Please some of your posts are terrible to read. A keyboard contains all the letters of the alphabet and spell checkers are readily available....! :cool:

Okay mate, I downloaded a spell cheek program just for You:P

I did what you said turned out to be like a 4.85 diff or something don't matter.

I'v decided after talk to a few mechanics with auto gear box and being a v6 it will have plenty of power and I got my lift yesterday and with the 33" tires it will have no problem at all.

Thanks for all you help.
