Rear wheel hubs
Turbo Mini Forums

Hi all,

I replaced the rear wheel bearings on the car just after the last trackday, as the original bronze cage for the ball type bearings failed. I used a set of timkins. from Minispares, I haven't used it much as we were moving house.

The car went for a MOT recently and the noticed slight play in the passenger side rear. I had a look last night and noticed that the hub slid straight of the shaft by hand, I presume this means the shaft on the radius arm is dickered...

if this is the case my next issue is that they are Hydro arms, and the shafts are NLA.

Thanks for any help.

I run a supercharger and I don't care the TB is on the wrong side.

Lock the bearings on with locktight.

A bit of a bodge, but a common fix (in my house anyway)

Is it a good idea?

locktite 638 bearing retainer, holds fast and requires a small amount of heat to dismantle,

Just checking that it's ok to use it on the shaft?

I've used it on a shaft.

I'd give it a go, the worst case is it doesn't work and you're back where you started. No damage done.

When my bearing was spinning on the shaft the whole thing got really hot (as you'd imagine). Once glued it was normal temperature.

You're only trying to stop it moving on the shaft, the bearing is all nipped up by the hub nut.

another thing I have seen done is to use a pair of hammers like in pannel beating and go round the shaft to give it high spots to gve the bearing somthing to hold onto. probably easier and better to use the loctite though.

Do the stub axels remove like they do on "dry" arms?
Two thoughts, (based on Joes comment re hammers) a small dose of a knuckling tool and a light cut to bring them back to size on a lathe may work, or have another made? There isn't a huge amount of machining involved?

If you do get stuck in future with radius arms we occasionally get them in for reconditioning. https://minispares.com/product/Classic/tra30.aspx

gav I looked at the link but the arm needs to have a good stub axel?

Hi Graham, +1 on Wil_h method that's how I fixed mine. Fine so far.

Easy enough to have the radius arm bored and a new stub axle made if it comes to it. Carl could help.

Thanks tom, I was chatting to Colin the other night and I checked the hubs over and the bearing is almost touching in the middle when you have the hub off the car.

The hubs look in good condition but I might try a new one to see if that nips it up. If not it could be a stack up of tolerances or a bad bearing

Ooo thanks Colin, I will measure them up

So I followed up on Colin's thread, got some shims and a the thinnest one I could get in the correct size does the job, no play. I think the tolerance on the new bearings meant they needed a blonde one to fit...

ball bearings why not find here: https://www.tradebearings.com/ball-bearings-catalogue.html I bought it before, the price is very good. You can also check here for other models https://en.tradebearings.com/

Maybe you need INA bearings from https://www.bearingforworld.com/ina/

I have two OE hydro rear arms. Happy to push the stubs out. There must sitting there gathering dust
