Hi everyone!

I know problems with axle nuts are common but I have not seen/heard any in real life. Now my car has this weird clicking noise which drives me crazy. My mechanic had no idea and suspects differential. Please can you listen to it and help me out?

My guess would be yes, it sounds much worse than mine did though before I performed the axle nut TSB.

I would not put a lot of faith in a mechanic that takes in a car with an odd wheel sound, and won't take 5 minutes to torque the wheel nuts. No matter what the car.

 

Could also be a bad toe arm link. Jack the rear up and try to wiggle the wheel.

 

Yup, that's the sound of rear axle nuts not tight enough. This is the sound of the wheel bearing shifting within the hub whenever you change directions and take off. Odd though, since you've got AP2 wheels, so I assume you've got an AP2. So far, only early AP1s had this problem of inadequate axle nut torque (some, but very few AP2s have this problem). Anyhow, worth checking the torque and re-torquing. Support some of the rear weight with a jack but leave the tire on the ground. Apply handbrake firmly, leave in gear. Remove center cap. Remove axle nut (36mm socket). A long breaker bar will turn the nut off even against the stake. Clean off the threads with WD-40 on both the nut and the axle. Lightly grease the axle threads and the big washer faces. Torque the nut back on to 221 lb/ft. Pound a new stake back in. You should notice that the new stake has shifted about 1/4" from the old one. Do this to both sides. Test drive it.
