Trying to get some info on a squeaky/squely real axle. It only happens at very low speeds like 5mph. Anyone got any ideas?

 

REAR* axle

 

Bearing in the axle shaft maybe or could be a LS wanting friction modifier. That's what I would think. May also be the bearing the pinion rides on.

 

What should I do? Cost?

 

First you need to try and pinpoint where it is coming from and whether or not you have a LS.

 

I have a lariat and it only happens when on driving all j can say is rear axle.

 

Jack the rear end up and take the e-brake off. If you can turn the tires with your hands and the other tire spins in the opposite direction, then you have a open rear end and should look at bearings somewhere in the system.
