Title: PFL Wheel nut sizes (front/rear)
Post by: MikeBoo on September 23, 2022, 19:55
Hello, can someone confirm the correct wheel nut sizes for standard PFL wheels?
I've checked the parts list and the front & rear have different part numbers.

I'm asking because today I've taken the rear wheels off and found that 2 different sizes have been randomly fitted to each rear wheel. Does anyone know whether the shorter or longer nuts are for the front or rear?
Once I know and get around to putting them back on, I'll see what's been fitted on the front and hopefully I'll have a correct set of front & rear nuts.

See my photo:

I am sure this was discussed fairly recently.

I hope that someone who can remember who it was will be along shortly!

Front 37mm and rear 42mm for FL at least and they are M12 x 1.5.

Evidently some garages/people are oblivious to the fact that there are different lengths for front and back, hence why you might find them all mixed up.  Rear wheels are wider/deeper so those are longer.

Thanks, my initial guess was that the rear would use longer nuts as the wheels are wider on the rear but I didn't want to make a costly mistake just by guesswork.

I'm glad it wasn't just me who asked this.

It ended up being my "What have you done to your MR2 today" jobs.

It's the little things that are so fulfilling.

Thanks everyone.

I now have the correct nuts on the correct wheels  ;D

It's scary finding this out, it's making me wonder what other horrors I'll find  :o

And now all correctly torqued to 103nm I imagine.
