D44 gear lube question....

[waynaferd]

On the closed knuckles, I was changing the front brakes and there looks like a fill plug in the back of the knuckle.....does anything go in that?

I don't have a manual or anything so I figured I'd ask here....Thanks!!

I thought I had seen somewhere that you put a thick gear oil in them but usually the seals that swipe the trunion ball on the knuckle go bad or leak so most of the ppl I have known have just pumped them full of hi temp bearing grease.

You can mix a slurry of bearing grease and gear grease then squeeze it in there. make sure your wipers are good. I just pack mine with bearing grease.

those knuckle seals are notorious for leaking......i put a mixture of 140 wt gear lube and bearing grease in mine
