Replace wheel bearings 87 brumby

Post by BrisBrumby » Sat Apr 03, 2021 6:01 pm

Hello, I’m looking to replace the front wheel bearings in my brumby. Trouble is, I can’t get the axel nut free! Any suggestions?
Thanks in advance.

Hey BrisBrumby,

36mm socket is required and a big long breaker bar, remove the split pin (duh), with the car on the ground and handbrake applied, jump up and down on the breaker bar you might even need an extension pipe to break it free. Once it is cracked then jack the wheel up before you remove the nut entirely. Take note of which way around the flat washer is placed under the nut, this is important on re-assembly. Torque setting for that nut is something like 196 Nm.

As above. The jumping bit is fun. Do not use anything smaller than a 3/4 drive breaker bar (invest in one!)!

Have fun!

Once you’ve got the drive shaft out, hammer the bearings out via the side they reside on. There’s a ridge cast between the bearings in the in hub knuckle. A decent pin punch will help out with this.

Cheers

Thanks for the helpful info, Turns out mine needs a 41 mm socket and I have borrowed a breaker bar from a mate. Fingers crossed...

I’ve never heard of a 41mm castellated nut on any Subaru before! Someone seems to have done a dodgy there.

Are they all the same size on all hubs?

Yes they seem to be. I’m beginning to realise it could be Franken-brum, but I love it anyway!, so, I got the hob and rotor off and the book says you have to take the knuckle and drive axel to a workshop to separate and to press bearings out/in - do you know if this is right. I have bought every tool know to humanity, including a bearing press and a ball joint press thinking I could di it all as easy as ChirsFix on YouTube, to be fair though, he has a Ford... any helpful advice greatly appreciated

No need for a workshop!

You can carefully hammer the driveshaft out with the hub in situ. Or, use your bearing press, that’s what a workshop will use. The trick is getting the hub level and secured enough for the press to do its work - and the press to be larger or high enough for the drive shaft to clear everything under it.

I hope this makes sense!
