  • Wheel studs - Marina based Roadster

    Information needed on changing wheel studs for longer ones.
    Back in the day when it had wire wheels the studs were shortened to deal with a clearance issue when the spline adapters were bolted on and the studs protruded which meant the wheels would not sit properly.
    Later upgraded to alloys but there was just enough stud length to make them safe to use.
    Today, I have purchased from the wonderful eBay some 15 " alloys, BUT they have a slightly incorrect offset which means that 10mm spacers will be required.
    Now, this in turn (it is never easy) means replacing the studs with longer ones.
    The question is..... How do you replace them. Is there a method that does not require the complete removal of the front hubs, separating them from the disc etc?
    The rears also look like a nightmare. I have never manged to separate a rear hub from the drive shaft using home garage equipment. Last one i did required so much force from the press that when it finally gave in, the bang was so loud that people from the nearby units came to see what had happened and the garage mechanic nearly had an accident.

    All advice gratefully received.

    usually the studs have a spline and are simply pushed in to the hub face. A good whack with a lump hammer should be enough to push them back out - but put a nut on them so they don't get mangled.

      What alloys and tyres have you gone for Jon?

      BTW The studs can just be knocked out with a hammer.

        Thanks guys for the reply.
        I see that a decent whack with my largest persuader will free them from the hub.
        My real question is about clearance. to actually fully remove them from there current resting place would seem to require a complete dismantle of the hub. Is this correct??

          If you hit them while on the car you will damage your hub bearings. Do it right. Take the hubs off and support it solidly and a few good whacks should shift them.
          For the rear ones take the halfshafts out, you don't have to take the hubs off the shaft, just support it with the shaft dangling. Helps if you have another pair of hands to hold things steady.
          Best of luck.

            I had to change one about 20 years ago and I remember that I had to pull the half shaft to get it out and fit the replacement.

              The front hubs should come off pretty easily the standard studs should fit between the hub and the disc but you don’t say what length and diameter replacement studs are. The rears are a little more problematic but the half shafts should pull out reasonably easily.
              Any spacer you use needs to be hubcentric.
              When I changed my studs to M12 ones, I dismantled everything, an opportunity to check seals and bearings etc. I felt it was better to press the new studs into place rather than to drag them through. Depending on your choice of stud, you may have to grind it’s flange down to sit properly in the hubs counterbore, best seen when it’s off the car.
