Okay I did search and I did find a few things. But It seems they are all a little different. My cruise control only works UNDER 40 mph. As soon as I hit 40, it turns all the way off and wont even light up on the dash. Does this sound like a speed sensor or a vaccum leak? if its the leak, where would I check it out yet? Need to get this fixed so I can keep my foot out of it on the highway... and do the brakes also since it feel like I have hotspots on the rotors, and get the tires balanced, and change out the EGR valve. Then I will be happy with the truck.

 

year make model and engine please

we dont have esp ..... lol

 

lol damn it. was tired when i wrote it.. 04 1500 4x4 qc with the 5.7 automatic.

 

anyone?

 

I would suspect the speed sensor in the driver side front hub.

 

So that means replacing the whole hub assembly right? Any idea of what a hub costs? I went to Pep boys yesterday, and they said the only sensor in the hub was the ABS sensor.

 

Yeah the abs sensor is in the left front hub. A new hub is about 90 on ebay. Check locally also and places online like rockauto.com

ABS does control the cruise.

 

couldnt I just replace the sensor? They were selling just the sensor at pep boys...

 

Nothing wrong with tryng as long as you can match it to your sensor.

 

I found the ABS sensor on Rockauto for $60. from Pep BOys it was $170.00 Big difference. I might end up trying to see if its the same on here once I have some spare cash at the end of September. I will def keep everyone informed on it too.
