Strange occurrence since I put my new springs in.

The truck rides a lot stiffer than previously, although not hard hitting any longer. Hoping that that will subside over time.


While on the highway today, I came upon a bridge joint, where the truck bounced a little from the deviation of the bridge, and the road leading up to it. The hit wasn't terrible, but enough to "un-set" my cruise control, which I had turned on @ around 60mph. I reset it, and on the next bridge, the same thing happened.

Anyone have their cruise disengage because of a bump in the road ? Nothing that I think needs fixing.... just really weird.

Maybe a loose connection somewhere?

Return spring on Brake peddle.

Or the BP disconnect.

Try readjusting your brake peddle switch. Sounds like it is too close and too sensitive.

Mine did the same thing. didn't fix it for a while, then my brake lights wouldn't shut off. i fixed the brake light switch, and boom, it fixed my cruise control as well.

Thanks guys.

I'll check that brake light switch and make sure it's not coming on while driving. I could always bungee the pedal to the steering wheel and go over the same bridge.....

and if I forget about the bungee, I'd turn right into a concrete wall on the side of the bridge when I hit the brakes

Just told the brake pedal up with your foot when you go over the bridge. But most likely it is the brake light switch. Just my two cents, Mike.

usually the switch just gets bent up a little bit or starts coming out. took me 5 minutes to fix it and i didn't have any tools.

Could also be slack in the tilt wheel. Mine sometimes does this if I move the wheel around up and down. At 1 notch in the tilt it has slack. Probably been in that position most of the time. Try another notch to see if it does it again or not.

Mine was the brake switch. Used a small hose clamp to keep it from slipping back. Worked for 1500 miles and then quit again. I'm out of ideas.

If you have a brake controller, check the settings, the inertia control (de-decelerate) might be set to sensitive, anything that activates your brake lights will disengage the cruise control.

Also I had a habit of resting my foot under the brake pedal to keep the lights from flickering when I went over a bump (driving the freeways)and messed up the switch adjustment making it overly sensitive.

Hose clamp fix is in the sticky.
