upgrade frontwheel bearings

[-Jo-]

i was bored this week (at work) and started with the new frontwheel bearings.

You can ask yourself , what upgrade ??? A bearing is a bearing. Correct! Butt, i changed the connection on the hub (i'll think its called that in englisch, the part where you put the front disk on:mrgreen: )

So , i changed the the french M7 to metric M8. That means you have to drill true the bearing and thats a ****** job because its hardened steal.

Dont start with that when you dont have the tools to do it.


To get an impression:

changed from M7 (fine) to M8 metric






drilled the bearing to 8mm


and glue/locked them with Locktite 603 (the strong one)




Why i do that ?

I dont like surprises when i'm on the road and with the power thats on board i dont take a risk.

hope you got something on this one.
Cheers !

Although I admire your patience and thoroughness Jo, I'd say it was a bit over the top. Correct me if Im wrong but doesn't that huge driveshaft nut clamp it all together as well? If you look at the 5/9/11's thats all that holds the bearings together!

Have to agree with Dave there Jo.

I replaced my N/S/F bearing last week and didnt have any issues with how it was assembled, especially (As Dave said) as i've had alot of experience with GTT's and how their hubs are assembled.
Having a friend with a 327bhp GTT and him having no problems with the bearings/hubs whatsoever would lead to think that the 21 set-up doesnt need improvement.

Still, best to keep busy eh?

maybe ur right but 327 aint what i'm after...

the main reson why i did this is very simpel. I'm gonna put a bigbrake set on it..that in combination with hugh torque...has anybody an idea how much vibration there is on the hub/bearing ?

like i told before, i'm not taking any risks.

Very true Jo, I'm not after 327 either....but then again i'm keeping the brakes standard size so I keep 15" wheels, smaller rolling radius=better acceleration. Thinking about beefing up the calipers mind LOL
I Still think, especially after seeing some massive crashes, the hub shearing away is impossible without killing the car in a flaming death crash. I've seen wheels snap and discs shatter, suspension legs and wishbones bent right under the subframe, creased subframes.....but NEVER a sheared hub.

Still fair play for giving it a go though!
