Sierra Rear Trailing Arms

Recommended Posts

The rear trailing arms from my Sierra donor were completely rotten, so I bought a pair of arms in better condition from a drum brake car. Unfortunately after having them all powder-coated I've just found out that the 100 mm diameter CV joints and stub axles won't fit the arms.

I'm, therefore, looking for a set of rear trailing arms from a disc brake car. I think it will have to be one of the later models as well so that the 100 mm driveshaft joints fit.

The outside diameter of the cv joint catches on surface of the arm. Tripod joints should fit all arms then the lobro joints come in 100 and 108mm diameters. I thought that 100mm joints fit all arms but obviously not.

Yes, with the drum brake arms I've got the cv joint catches on the surface of the arm and you can't insert it fully or it locks it up.

I thought I must have had 108 mm joints but a quick check and they measure 100 mm diameter.

Many years ago someone, Chris Brown? did an article on fitting disc brakes to drum brake arms, it may have involved a large hammer.
