Lube Question Freightliner Universal Joints

[Triker56]

I use a Harbor Freight air gun

I did get both fittings lubed on both u-joints using the air operated gun with flex hose.

You do know Freightliner manual says to not use high pressure on the drive line.

From Manual:
U-Joint Lubricating

1. Wipe all old grease and dirt from each U-joint grease fitting.

2. Use a hand-type grease gun, or a high-pressure gun with a low-pressure adaptor, to lubricate the U-joints.

NOTE: If a low-pressure adaptor is not used with the high-pressure gun, the U-joints may not receive enough lubricant.
