The Stovebolt Site Forums The Parking Lot Big Bolts Axle and brake swap between diff housings

Hi All

I have a 5.4 final drive diff with 10 lug wheels at the back with the massive brakehubs in my 51 2 ton equivilent.

I also have aquired an 8 lug rear end from a 4.5 ratio dually 1 ton. (or 1.5, Im not sure). The spring hangers are spaced the same but I want to keep the rear rims and big brakes.

Is it possible to take out the half shafts and brakes from the 5.4 rear end and put them into the 4.5 housing and have it slide into the splines perfectly. The diff centres are non swappable between the two as they are different shapes. The housings are the same witdth.

Happy to put up pics of the two if need be.

Cheers

Damo

I don't have any half axles out, but I am quite sure the half axles in a 2 ton are larger in diameter than the 1 ton. If you have a 5.43 (38-7) you are very fortunate. They are hard to find. I would put some larger tires on it and be done with it. It will go as fast as you want to go. I looked in the parts book, and there are 2 pages of different half axle sizes listed, so it is very unlikely the change you want to make is possible.

Thanks mate. I might still rip them out and compare and post back in case anybody else is interested.
