Replacing Sierra wheel studs?
kurt - 26/4/06 at 07:56 PM

One of the SVA fails on my build was the front studs being too short due to the alloys I've fitted. I've got the old ones out but the new ones from Burtons are impossible to get in. I've tried using an old wheel nut to draw them through but the whole lot binds up despite lubing them. Any ideas? (liquid nitrogen would be useful)

Cheers, Kurt

If you remove the hub, you can either press them in a fly press if you have one. Alternatively I have used a large hammer to good effect

Stick the studs in the freezer and heat the hub before attempting to fit, every little bit helps .

Ditto...FBH...


If you've got the bearings out try heating the hub in the oven to about 150c and studs in the freezer.
Works for putting flywheel ring gears on !

Wheel studs aren't that the bolts that hold the wheel??

How do they measure it? I know mines aren't plenty long...

what''s the limit??
also have alloys..

I did this a few weeks ago, though I did'nt get my studs from Burtons.
After breaking a vice trying to press them in I did them on the car using an old wheelnut, like youve tried.
However you MUST put some slippiness under the nut, I used 3 nice shiny washers greased up between them and bingo!
They are very tight but I got all 4 wheels done in a couple of hours, try it

yep, stack of washers with lots of coppaslip on them and a pneumatic impact wrench (windygun) will soon pull em in.

i used a piece of pipe and a bit of 1/4"
plate drilled and countersunk for wheel nut , loads of grease and a big flexy bar
certainly gets you a sweat on !!!

how can i check if my studs are up to the rulez or not?

The nuts i use are special for alloy rims.

They are blind ones (you cant see how much threaded bar is in them.

Also my rim covers all the nuts, but i´m sute SVA man will take that one off to check???

You should have about 5 - 6 full turns of the nut before it tightens.

Dave J - 27/4/06 at 04:20 PM

The general rule for minimum thread length is it should be equal or greater than the diameter of the stud, bolt, screw etc.
ie; MINIMUM stud thread length for M12 nut to screw onto = 12mm.
I prefer just a little more to be on the safe side.

thanxs..

its clear will try the 5/6 turns

kurt - 28/4/06 at 05:35 PM

Mine failed on 7 to 8 turns so 5 to 6 is not enough. The length if thread equal to the dia is what they are .looking for, minimum. i.e. M12 nut needs 12mm thread minimum.
