    How to regrease SN95 hubs.


    Assembled Front Suspension


    Remove 36mm Axle Nut


    Turn Bearing over to access back side


    Richard Pedersen made this trick tool at NASA, but you can also use a screwdriver between the inner and outer race to pop the rear race off.


    Rear Race removed


    Rear Race removed (2nd shot)


    Pry on rear bearing cage to remove rear grease seal


    Rear bearing cage and grease seal being removed


    View of front race from behind


    Use 1 1/8" socket to tap out front race


    Remove front race.



    Pop out each of the ball bearings from the front bearing cage with a small flat blade screwdriver.


    Clean everything with brake cleaner so you don't mix grease


    Regrease with your favorite synthetic racing grease

    Awesome write up Marshall! The pictures are defeinitely helpful. Is it worth buying the tool? How often do you regrease yours before replacing? Grease every year?

    And how many tries did it take you to get your bumpsteer corrected?:shock:

    Thanks Marshall for posting this. I am going to remove the one I borrowed from Sam at TWS (thanks Sam) this weekend and redo my old ones. I will get yours back Sam via UPS next Tue.

    As a heads up, I recommend pulling apart the hubs and regreasing them before you ever run them. Every hub that I ran for a while then regreased still failed. I've never failed a hub that was set up with proper grease from the start. The hubs that are on the car currently have been on there for a long time. I haven't pulled them apart to freshen them up either...

    Regarding buying the "tool". I wouldn't. I just used Richard's cool tool to say I did. You can do the same thing with a flat blade screw driver and hammer in less time.

    I agree with Richard. My hubs get stripped and regreased before ever hitting the track. I have two seasons on them and they are still fine. It's a function of the grease quality. After next season I will flip the bearings from the inner race to the outer race to even the wear.

    I do carry an extra hub, just in case.

    About six. I ended up with about as much spacer stack as I could fit with the wheel...

    I buy them, grease them, run them for 2 seasons, flip the bearing balls and run another 2 seasons...

    My memory is a bit fuzzy at this point but I believe my current front hubs were installed in late '04. Before I started using good grease on fresh hubs, they would last about a year.

    Can you purchase the grease seals? I removed a hub at TWS and there was grease all over outside the hub.

    No, you can't buy any parts for the hubs since they are "non-serviceable." Be very careful taking them apart.

    The reason I got into regreasing the hubs in the first place is because I had a pair of hubs with such thin and crappy grease that it melted and flung out all over the place. It was everywhere including the brake discs, calipers, inside the wheels, etc. My brakes faded away at TWS and I had to come in to see what was wrong. Proper grease stays inside the hub. A grease seal is to keep contaminants away from the grease, not to hold the stuff in...
