Allpro Dual swing failure

Have had issues with my dual swing rear bumper on my 06 taco. Have one side locked up. Pulled bumper to get to grease zerk and refuses to take. No core, electric grease gun is bypassing. Maxed out pressure. Anyone have a diagram of what I'm working with inside? Just bushings or is there bearing?

 

Undo the nut at the bottom?

I'm not familiar with their setup, but some use a tapered bearing, others use straight roller bearings, or maybe even ball thrust.

Maybe one of them is fucked?

 

I had nut 90% off and still no luck

 

Replace the zerk? They get plugged/jammed sometimes. (assuming you mean it won't take grease)

 

^^^^^^^^^ What He said^^^^^^^^

Take out the zerk and use a wire to see what is behind it - maybe rust or debris
Replace the zerk with a new one......

 

Pull the zerk off

try to add grease with a grease needle

 

Zerk was fine. Finally got the spindle out with forklift and airhammer. Just brass bushings. Siezed to the spindle.
