Twelve months ago I had all of the wheel bearings replace by a mechanic that specializes in sport cars. Last week the passenger side rear wheel nut came off the axle and I could not keep the car on the road. the mechanic claims that they used new nuts as I was charged for new ones, The bearing was toast. This time when he replaced all faulty components, he said he used lock-tite and place a spot weld on the nut-axle.
Strange, the drivers side also had play in that assembly and except for the axle, there is not much holding the wheel in alignment.
The only only unusual thing happening to indicate that this was happening was that the car would swerve left or right when blasted with a gust of wind from a truck or nature.

 

Emil,

You're probably allpissed off about this, I don't blame you. Maybe you forgot to ask a specific question that you might have?

In the meantime:
1. You must replace the nut. He did so.
2. This nut requires a lot of torque, 325 foot pounds. It can and will self loosen if this is not achieved.
3. The tire/wheel needs to be on the ground for this kind of torque. Maybe pros have compressor/impact wrench that can deliver this, I dont.
4. My torque wrench doesn't go this high how can I measure it?
Set the nut with impact wrench while jacked up.
Remove center badge from wheel.
determine size of ratchet needed for your 1/2 inch ratchet wrench.
put wheel & tire back on the car. Tighten its lug nuts.
Lower car.

***Decision point****
The torque applied is at the limit your silver off the shelf female ratchet and the extension can handle. (Ask me how I know ;-)) I've had the sockets break, and the extension's head shear off. Btw the socket gets too hot to handle too be careful.
from my experience you should plan on one of them breaking. Have a back up.
OTOH- they sell sturdier sockets and extensions for impact wrenches.
Open question to the forum: may we assume these special sockets can easily withstand this torque?

Ok car on the ground. 1/2 inch ratchet clicked in at 90 degree angle to the extension socket combo. Slip the socket on the nut through the access provided by removing center badge.
Look for a sturdy pipe as a lever. I use the extension from my 2ton hydraulic jack. The extension is 3 feet long.

Calculate where to apply pressure on the extension. If you're 200lbs, and want 300 foot pounds, 200 x 1.5 = 300 so mark a spot on the extension 1 1/2 foot from the center of the ratchet head. This = 300 ft pounds. You can figure out the rest.

I'm really surprised the nut fell off. A slightly loose nut sends strong signals immediately IME. Car steers itself with accelerator pedal, left right turns are scary as hell, feels like you just drove over uneven pavement to say the least.

Ah not trying to stir things up. Tell us more about your question mate.

JTIS shows the axle nut torque at 304-336Nm not in foot lbs.

 

Thanks!!! That's then 248 ft lbs.

I did the the same as Johnken when I changed a wheel bearing; I borrowed a 3/4 socket and bar and worked out where to stand with my body weight.
