Need some ideas to make up something to move my DATTO.im moving house in 2 weeks but my diff is still at the shop.i already have a 50mm stainless bar with a hub welded each end and the wheels bolted to it and sitting under the car in there right place.was thinking a 50mm bearing then a 4 link bar from bearing to brackets but finding it hard to find cheap bearing/carriers.any1 have any ideas?

Nah dolleys are no good Its the fact I need to bolt this mocked up axle to the car.so was goin to glide a bearing onto the axle then bolt to the car.atm it's just sitting there not bolted to the car

Need to find a Center bearing setup from like a 4x4 like this! Am I on the right track now?

Yeah that's more like it

Another problem can't wait the 2weeks for delivery as I need to move the car next thursday.any1 got anything similar laying around?

Find or borrow a standard diff. Temp bottom arm terminating with a plate and bolt or tack weld plate to leaf spring perch. Similar for your watts link pick up or panhard. Couple of blocks of wood wrapped in rag as springs and you should be right.
Cheers.

No rear leaf mounts it has a half chassis with 4link.will be using timber for springs tho

Read it again Brent. You use the bottom pick up point at the chassis, fabricate a temporary arm that will splay out to the leaf spring perch on the donor diff. You may not even need to support it laterally if there is enough angle on the arms.

Managed to move it with out a scratch.just threw a Borg Warner diff I had laying around under there then blocked up the chassis.then winched her straight up onto my car trailer :)
