G,day, all, this thread with pics is magnificent. I will be having a crack at my CV and axle seals as soon as my parts arrive as I have grease dribbling down the brake shield. I have two questions.

1. The hub seal definitely fits in with the two lips toward the CV, and the one big lip into the hub, doesn't it?

2. I have innox Extreme pressure M8 grease which is for farm machinery, marine, CV joints and brake wheel bearings. (Bloody expensive, but as water crossings are on the cards, I think it will be worth it). Has anyone had any dramas with it?

1. Big lip on the hub seal faces the CV.

2. That grease is high temperature rated so should be fine to use.

Yea when I removed mine it was big lip (seal end, flat side) towards the cv.
Look at it like this. You use seals to keep oil grease etc in. The oil is thinner than grease so you want to keep the oil in the diff, so you place the seal as if the diff was a bearing, not the cc. Hope that makes sense..

Thanks K I think I know what you're saying and you are correct, though in this case I think you are referring to the axle seal rather than the hub seal from the previous post.

I asked because I saw an experienced bloke fit a hub seal with the two smaller lips onto the vertical face of the spindle. Which is opposite to what was on my Old Trol when I took it apart to repack the bearings. The one big lip was rubbing on the spindle ,so I replaced it as such. so I'm still confused.

Hi Mudnut,

Do you mean this seal mate?



in the pic below you can see where is has rubbed on the CV. Note that it is shaped to fit straight onto the spindle and the "Lip" is facing towards the CV to create the seal when spinning.



In the pic above you can also see the inner axle seal still in position in the diff housing. that is the bugger that most often fails and is the cause of the weeping of Diff Oil down teh inside of the inner stone guard. it is a bugger that the whole thing comes apart to get to it.
