Finally got around to flushing the brake lines and clutch line on the weekend. All was well ,,,, that is,,,, until I snapped a wheel stud when attempting to remove the rim from the rear end. Does anyone know the dimensions of OEM wheel studs for a 1985 GSL-SE (rear wheel studs)? And more importantly where can I purchase quality rear wheel studs and acorn nuts from a reputable company? Do not want any of those shoddy knock off parts from China.

Be careful out there!

First one if you want 1.5" (26-113A-8595)

Its like 10 CAN with exchange rate lol

You can also get ARP studs from JRP if I am correct

 

You should be able to get wheel studs for that from any parts store that will be good quality. I know I replaced some a few years ago in my gsl-se rear axle and I just got them from my local carquest. The nuts are just a regular M12x1.5 nut.

 

Thanks guys for the input.

Buggy you are correct. On a whim thought I would inquire with Parts Source and much to my surprise they had both lug nuts and wheel studs in stock. Now,,,let's see what else I can break when I go to install the replacement stud.

 

I have a special tool for installing wheel studs. It's like thick bearing that goes over top of the stud with a taper for the nut to seat on. The bearing rides on the hub flange and you use the nut to pull the stud tight. If you can find that tool they are worth buying. Not very expensive if I remember right.

 

Big *** washers and a regular Metric nut(open ended of course!)..BLippp..done

 

^^ This. Took me about 20 minutes to do the rear studs (one side) on my RX7 a couple years ago - including jacking up the car and removing the wheel, and unbolting the caliper to swing it out of the way. I seem to recall having the caliper out of the way gave me a spot to rotate the rotor to to bang the studs out without them hitting anything. A small sledge (I think mines 2.5 or 3lb), whack the old ones out with a light swing or two (since I wasn't re-using them, I didn't care about flaring them a bit, but if I had, I'd have just put an open nut on flush with the end and hit that), feed the new ones in from behind, cinch them in a bit with an impact wrench and an open nut, then cinch it the rest of the way by hand. Took me twice as long to drive to the parts store a couple or three kms away and have the counter guy hunt in the back for right studs (took him several tries).
