New Wheels, Stripped Threads

[letemlaf]

Hi guys

I bought a set of advan sa3r second hand 17"

My old nuts were too fat to fit inside the new wheels so i bought a heap of new ones.

The ones i bought seem to fit perfectly, but i have just taken the wheels off to spray them black and the front right wheel had 2 nuts that were so tight, even after using wd40 and a bit of oil to lube them up we could bearly remove them by jacking it back and forth until it finally came off very reluctantly. It wasn't like they were tight for a small part of the thread but from start until finish.

2 of the studs are partly stripped of their threads and need replacing as well as the 2 nuts.

I'm wondering how this could have happened so i can avoid it in future. im not a newbie to wheels and know not to overtighten or cross threads and what not else.

Btw, what are the stud sizes because i need to buy some more (and hopefully from a wrecker).

did u lift the car with all the bolts off? this can do it i think

im not sure what u mean, when i was taking the nuts off/on?

the two studs/nuts have been cross threaded.

shit happens.

this might have been caused by you putting them on wrong, or the threads on the studs/nuts not matching, or even being way over tightened.

just be careful next time.

when removing a wheel, i jack it up a tiny bit then crack/loosen the bolts while its on the ground (always doing opposites), then jack it up then undo it all the way.

when putting it back on, (again doing opposites) i tighten the bolts slightly to around 30% torque while the wheel is in the air, then drop the car and do them up all the way.

are you sure you used the correct pitch nuts? You said you used new nuts , were they all the same ? Nissans use 12x1.25 mm pitch, same as Subaru, others use 12x1.5 mm pitch.

You can buy the studs new from Nissan

i hand screw them in 90% of the way and only tighten the last bit by hand and i only tighten them enough to hold and check them the next day so its very unlikely i've overtightened them or crossthreaded them.

I do them in opposites from each other but i crack them on the floor then jack right up to unscrew and losen, that could do this?

The nuts are 12x1.25

cheers

Its very hard to strip them by overtighting them you brake the studs first.

Thats the way you should undo them, do them up. Maybe you had 2 different studs on? someone changed them to 12x1.5 mm before ?

Ye, unless you cross threaded em, possible wrong studs were in there?

Other than that... being a bit over zealous on the tightening wont cause it as above.

Sounds odd if your 100% you put em on correct and they came off good also

Hi,

Had a similar problem on my much modified RX2. I had installed longer studs with a different bolt PCD. The long and the short is that the taper where the nuts seated in the rim was different to the taper on the nuts. Therefore when tightening the nuts the tapered end was forced narrower causing that part of the nut to bind on the stud...check the tapers and compatability of the two tapers.
