Warning to those with Superlifts

[lekmedm]

Just installed the Rustys Upper Control Arms to correct the pinion angle. Had to cut off the small mount for the sensor and weld onto the new one, mine is a 2010. Don't know when they started putting the sensors on the links and A arms?
Had to drop the fuel tank in the rear to get the one bolt out. Other than that it went pretty easy. Pinion angle now straight!!

Cool! I wonder if you'll hear or feel any difference.

What sensor so you have back there?

Electronic Stability Program and Traction Control System. It has a position sensor on the left UAC and right Upper A arm and a position sensor on steering wheel. Don't know when they started this maybe someone here will know. I think thy is why superlift had AEV come up with a module to hook in to the steering sensor and recalibrate for tire dia. Some with larger tires freaked out the brain as the newer models have gotten more sensitive.

Found this in the manual.
ESP uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESP applies the brake of the appropriate
wheel to assist in counteracting the oversteer or
understeer condition.
Don't you just hate it when someone or something is trying to help you drive.

Here is a couple pics of the wonderful sensors. As you can see I spent hours detailing underneath.

After addressing a YEAR'S worth of bad pinion angles on my Ramcharger, and even building a custom double-cardon driveshaft for it, this thread is suddenly VEDDY, VEDDY, INTERESTING to me!

NOT a Superlift I know, BUT... anyone familiar with any issues on the Daystar 2" lift? I'm looking FORWARD to it, but a) it's my DD, so it's GOTTA go, the moment it leaves the garage, and b) it ain't PAID FOR yet!!!

The warranty is expired, which is why I've waited 3+ years to tackle this, but I REALLY don't wanna start messing with driveshaft angles on my DD hotrod!!!

Nothing to worry about with the 2" lifts. Mod on my friend.

OK, so when I am gently accelerating up a hill (actually applying throttle to maintain speed) I get a heavy vibration from the drive components. It feels like I am running on grated asphalt ready for repaving. Is this a symptom of a bad pinion angle? I'm running the OME HD with F150 Monroe Load Levelers - so it is close to SL height without any driveshaft angle adjustments.
