Thread: wheel speed issue.

Eiher that or you are doing a really big burnout!

Tyre size difference, tyre pressure difference, doesn't have to be much i think.

Hi Phil,
I would say electrical noise or magnetic field causing interference, has it got a fault code too for that wheel?

Hi Phil
Another way to check.
Jack the wheels up one at a time,handbrake off ease it into gear and watch the speedo reading at the given speed.If its a sensor not working the speedo will read a very high speed for the faulty wheel sensor as it cant reference the wheel speed by dividing it by 4.That is how I worked out which one was faulty on my D2.When I bought my Nanocom fault codes confirmed the same sensor.
Obviously CDL MUST be unlocked and wont work if you have a True Trac or Detroit locker.
Goodluck

nope, no faults, thats the weird thing... the fault i was chasing i thought was in the front end, during the 3 link install i also did the swivell preload, i removed the only shims that were there, and after that the abs and tc lights stayed on, till today? front end didnt show any faults none at all when i did the test the wheel speed issue was all i found

if it was electrical noise or magnetic field what would i be looking for cause wise

Why wouldn't you just unplug the LR sensor and see if the speed is still there? If not, then its in the sensor I would think.
