Rear-end locked-up after installing my new Wheels!

Assuming the car is in the air while your installing/testing the new wheels: Is the shifter in gear?

Back off on the lug bolts until they spin, and take a look at what is going on....

Are they hitting the Konis???

 

If the car is not in the air but you jack up one wheel at a time, even if the car is in neutral, the limited slip diff will prevent free rotation of the lifted wheel.

 

That would be my first question. (D'oh!)

I installed the Superformance wheels last spring, and I love them. No problem going on/spinning freely either front or rear.

Have you tried putting the original wheels back on to see if the problem is really with the wheels?

If it's just a matter of having the car in gear when you try to "spin" them, don't feel bad; it wouldn't be the first time that someone assumed the worst-case scenario when the "problem" was really something quite simple. (Ask me how I know.)

My next guess would be that the new wheels knocked against the rotors or calipers, or are in some way interfering with their proper operation, causing the rear brakes to lock up.

Please keep us all informed. I'm interested in knowing the cause of the problem - and whether I need to be vigilant about my own Superformance wheels, if in fact, it is a problem with the wheels themselves.

And don't feel bad if you simply forgot that the car was in gear! As I said, you wouldn't be the first 308 owner to make a simple mistake like that!

 

Another obvious check - are you certain you put the new fronts in the front, and new rear wheels in the back?

A 16" front will fit front and back , , full size spares are 16 X 7's so they will go on anywhere. Of course that is just to get you home......

If the wheel studs are too long they will hit the aluminum rear wheel bearing housings and nothing else.

Pull one wheel off and put a wheel bolt in from the front , measure how far the bolt pokes through the back. Now do the same with the original wheel.
Compare the difference , , , a 1/16th of an inch probably wouldn't hurt but more would be something to fully investigate.

 

Had the same problem. New wheels were "thinner" where lug bolts went thru. Rear bolts went further into the threaded holes and interfered with something in there. I cut the bolts shorter, problem solved.

 

Funny that mine did the same when I changed to 16" wheels on my 1980.

Mixing up front and back wheel studs does it. Front studs are longer and when used at the rear wheels dig into the brake disk, binding the wheel, locking it up, potentially warping it.

 

Fave - has this been corrected yet? If yes, what was the problem?

odds are,

Yep,




Frank got the bolts mixed up.


Done that,

Ahhh, its a thing of wonder... get all the minds together and without even seeing the car they come up with the right answer to the problem.

 

Frank, are you certain those were OEM rear bolts?

 

Thats what I thought .......... I go to great lenghts to make sure I am putting things back together exactly where they came from only to realise I am working with stray / incorrect parts. Most 308's have had many owners before we got them. Who knows what drongo did what to these cars in the past.

 

OK, now lets see a pic with your new shoes!

 

I doubt there are 500+ 308s running around (or stationary in your case) with these wheels on them.

He cant get it out of the garage to take a picture, sorry I couldnt resist.

 

yeah I should've read the thread, too lazy
