BMR Tech Tip: Check those axle-to-spindle retaining nuts!

BMR Tech · Mar 22, 2017

Popping, squeaking, wheels wobbling, vibrations and many other symptoms can occur when the rear axle to spindle/knuckle retaining nuts lose their clamping force.

I am seeing this almost on a weekly basis at this point, both with stock and aftermarket set-ups.

I have found that installing a new nut and torquing them to 150ftlbs + 1/8 turn with Red Loctite has been the best for myself and our project cars.

I recommend marking the nut to the shaft so you can inspect them occasionally to ensure the nut does not back-off of the threads.

Dealer just replaced my half shaft nuts and my creek/squeek under accel or decc is now gone. For how long, is anybody's guess, LOL.

Had a clicking sound at low speeds ~10-15mph and the rear axle nuts weren't torqued properly.

Just ordered some new fastners. Thanks for the tip. I put new halfshafts in last year and reused the stock hardware. Did not put many miles on the car before winter, so hopefully I have avoided some drama.

Why use red and not blue? Wont red make it near impossible to remove?

Wow!!! Mine makes a creek/slight pop noise.m.i know its coming from the axle....but never thought this would be tge cause. Mine really only does it after i back up, and then start letting the clutch out to pull fwd....wow, checking the tq when i get home!!

Red because it's got a higher temp rating and on a nut that big it wont be tough to get it off if needed.

So I replaced the LR hub on mine last night and the factory nut was fairly easy to remove. Had some weird popping when turning left and starting to roll out from a stop. The hub/bearing didnt feel crunchy but there was grease all over my spindle and the bearing smelled like a burnt diff.

Ill be checking this prior to installing wheels next week. Im getting the 5mph clicking while turning. Whats the size of that spindle nut ny chance?

Just wanted to throw this out in public for people to see.

Seems as if several people are already providing some feedback on this very thing.

I figured it should be posted, since I seriously deal with this issue every week.

I had one loosen on my '04 cobra. It was noticeable the moment it happened. As soon as I accelerated it felt like I had a rear tire going down.
