Im converting to 4WD this weekend and have a question.

Currently I have a '96 2WD with good+ brake
The donor vehicle is a '87 with no brakes

Will any brake parts cross over, or do I need to buy everthing from the hoses down.

Thanks

Jesse

I just went to quadratec and compared the OEM hard parts list, it gives different #'s for the '80s and '90s.

But if I have whole assembly does anyone know if they will but up as a complete unit?

Click to expand...

it will likely not work unless you can come up with a knuckle from the same year as the new front end - the difference is the unit bearing thickness and how that forces teh rotor to line up with the caliper, and the knuckle has quite a bit to do with that...

id say use your knuckle, unit bearing, and everything from the front axle "beam" on the 2wd, but there is no provision on the 2wd "hub" for an axle shaft and that is the whole point of the swap - to have front axle shafts is it not?

good luck!

I took the d30 from my 88 and put it on my 94. in order to use my good brakes i had to switch my nuckels.

the rotors are the only thing that are different, and its just spacing, the wheel bearing assembly is also spaced differently, so the end up lining up the same

The 87 dana 30 will be of the vacuum disconnect variaty. It would probably be easier to fab up a cable shift mechanism than to mess with the vacuum shift.

Thanks for all the responses guys!

I figure I will just use my current Knuckles off the 2WD to still use the brakes (it seems they just have a big ol' 'plug where the axle shaft goes in)

in regards to the vac disco, the stock vac disco axle shafts are 3 piece right? 2 little and 1 large right??

And the non disco shafts are 2 piece?? a tall and a short?

Because I think my buddy threw the newer style shafts in the back but I didn't notice them until I went out just now and was looking around in the heep.
