Outer CV Shaft Overheating (Driver side)

[Fraptor2010]

Good Day everyone,

I am looking for some help. We have tried everything and nothing seems to work.


The driver side outer CV is overheating (part is circled in the picture). After about 45 minutes of casual driving it's hot to touch, so hot that you cannot keep your hand on it .

The other side is not hot at all. Brakes and rotors are the same temp all around.


We have tried 3 different axles, 3 IWE Solinoids and 3 Hub assembly's. (Ive tried aftermarket and factory Parts)

I have replaced all rotors and brakes.

We pressure tested the vac lines and everything is good. No grinding noises at all.

Also have had an alignment done.

My front diff has been removed before, could this be shifted over more to the driver side?

Has anyone had this issue or know anything that we are not checking?

Thanks in advance.

Ooooo... I know stuff here.

I'm assuming the axle must be spinning in 2WD? What about the passenger side?

What vacuum pressure do you read coming out of the valve where the vacuum tubes connect (upper driver side firewall).
What pressure do you read at the driver IWE connection (disconnect from IWE and read large tube).
What pressure do you get at the passenger IWE?

Yes spinning in 2WD. same thing occurs in 4WD just heats up faster.


I will get the shop to get me these numbers and get back to you,

Thank you!

Are both axles spinning in 2WD or just one?

Interesting problem, with your CV axle installed do you have any movement in and out of the center section?

The axle in the picture doesnt look new. If you have a temp gun check temp on brake rotor compared to the other side. Heat is transmitted from the rotor to the axle. On my Gen 1 I had a bad front left caliper, caused the front left pads to wear much faster then the front right.

nevermind. Just saw you checked brake rotor temps.

How many miles? Is the hub/unit bearing going bad? If it is, that could be causing the heat?

I cant seem to get them to look at it with everyone off work, so i will try this myself.

The Hub Asssy is NEW. i have tried 3 different ones with the same outcome.
