MG MGB Technical - How to replace rear wheel studs

SO... I replaced the leaf springs on my wifes 79 MGB. All went fine except it raised the car considerably. Then I kept smelling rubber burning. I found out that since the car was raised the Left side tire is rubbing

I need to install wheel spacers.

I just received the spacers and new studs in but now need to pull the old studs.

I'm at work and will start this project tomorrow. I wanted to get a little info form anyone that has done this before I started.

Can I just hammer the old studs out with the hub in place?
Is there enough room behind them to come all the way out or do I need to tear off the wheel hub?

If I do need to take off the wheel hub how hard is this and does it require and special tools?


Thanks in advance for any advice given.

Never had to do this, but if you leave a nut on the studs so the hammer doesnt touch the threads you can knock them out without burning your bridges.

I would be concerned about where the tyre was rubbing and why, rather than trying to make up for it by fitting spacers aand longer studs.

What size tyres/wheels? Up to 5.5 and 185 tyres there should be no clearance issues. I had a car with 6" wheels, then there was only slight rubbing on the inner arch, when cornering hard. When the inner diff gears wear in the carrier, the rear wheels devlope a bit of negative camber, the tyre can rub on the inner arch, and the brake drum on the back plate. Jack up, hold the wheel top and bottom and try to rock!!!
If you are still going down the longer stud road, take the hub off and press out in a big vice. That way you don't damage the bearings.

Raising the car should reduce the chances of rubbing, not increase it. For spacers to have any effect the tyre would have to be rubbing on the inside of the arch, and if one side is doing that then the other must be close to rubbing on the outside, spacers making it that much worse. I suggest you have got something wrong with the relationship between the new springs and the axle.

As for the increase in ride height whilst that is all too common with replacement springs, it could be another indication that you have assembled things incorrectly.

I will try to explain as best I can

there is a "Bump" on the inside fender well. It is for a rubber bumper. I think for the car Will not bottom out

Before I replaced the suspension the "bump" road lower and did not hit the tire.
After I replaced the leaf springs the bump was higher and rubbed against the tire where the tire bulges out from the wheel

I uploaded a Pic of what I am talking about


Anyway I was able to put the spacers on and everything is working fine now.

That's on all cars, although the upper part looks a bit odd, possibly because of bodywork changes. You may also have steel wheel hubs on a wire wheel axle, which *will* put the tyres closer to the inside of the arches. Spacers will have corrected that.

I dohave steel wheels
