Folks here are good, but not mind readers.

 

Year and model please.

 

I'm guessing older car(since newer are sealed), and in that case you've posted in the wrong section.

 

So please specify year and model and perhaps someone can help.

oh ok...I checked the book and it says they are sealed bearings.

 

It's a '98 OBW...

 

I don't think my mechanic is trying to rip me off...I just think he wants to spare me the gory details....

 

 

Cheers!

Personally I use the grease packed with the bearings and I have never had a single repeat failure. I am extremely attentive to cleanliness and I have quite a bit of training with regards to bearings. One thing that no one ever listens about is how *little* grease you should actually be using. 30% of the cavity should be filled. With the grease that's packed with the bearings that's about what you will have once it flows out to the seals.

 

Seal surfaces are another area no one pays attention to. They need to be very clean with no signs of a lip groove. Few are in good enough shape to run 100k in a harsh environment once the first failure has already occurred.

Well...now I know where the Welsh word 'slipuducuppadalip' comes from...

 

Engineering thoughts like that are real headaches....but I guess we gotta think them anyway.... :-(
