| − | Here's how to make a fixture and rack for straightening a rear end housing.

| − | The cart pictured below is an old gas cylinder cart, bought at a garage sale. An I-beam is welded to the gas cylinder cart.

| − | To prevent any mishaps involving slippage and gravity, common jackstands are cut up to wrap the leg of the I-beam.

| − | A straight bar is necessary. This hardened and chrome plated bar is about five feet long, and 1.5" in diameter. It's available from McMaster-Carr for about $115.00.

| − | Then, make some inserts. These are about 2" long, as to provide some load bearing area to lessen wear caused by repeated use. For this application (10-bolt Chevrolet), the ID is 1.504", and the OD is 2.894".

| |
| − | Another insert was made with the same 1.504" ID, and dimensioned to slip-fit into the housing end. This same set of inserts and matching bar can be used as an alignment aid when narrowing rear end housings.
| |
| − |
| |
| − | The inserts are then clamped in the bearing saddles, and the bar slides through them. The fit should be nice -- the bar should slide through easily, but with no noticeable play.

| − | The housing end insert slides over the bar, and indicates how much the end of the housing is bent out of alignment.
