Got a 1990 Toyota Pickup, 4x4, 22RE. Some of my Zerk fittings on my drive line are not letting any grease in. Everywhere I call want me to take them off and bring them down, but I only have one vehicle so I cant do this.

Anyone know what kind they are?

 

Take off the fittings? or the drive line?

you can drive without the fittings

 

the size thread they are depends on if they are factory u joints or have been replaced.

Pull the ones off that are clogged take them to your autoparts dealer so they can match them up.

 

or buy an assortment kit and match em up. pretty sure to take em off, its an 8mm socket

 

Thanks guys I got it!
