My Raptor is bouncing/shaking!

I think you have massive confusion on what exactly a wheel alignment does.....

Yeah that’s alright man that’s why we have forums like this with more experience people

What @Swacer said.

alignment won’t cure or remediate a bounce / vibration like you’re describing. bad alignment will very quickly wear either the inside or outside of your tires, cause you to drift or pull in one or the other direction most commonly.

bounce that you’re describing can be caused by
poor tire balance or no balance.
tire out of round
wheel that is bent or out of round
tire/tires that are grossly overinflated.

The 35” KO2’s are hard to balance, I can only imagine the heavier KM3 aren’t any easier. Unfortunately when this happens, 99% of tire shops are completely unprepared for diagnostics. If you’ve changed “more than one thing” they’re going to try and blame your parts (plural) and feign ignorance.

Make sure you have wheel weights on all the wheels. I’ve had a shop forget this. If there are weights then chances are you probably have either an ineffective wheel balance or possibly a bad tire.

Less likely, a bent or out of round wheel. I had an old Exploder with a bum wheel and caused that shake you describe when it was front mounted. in the rear, it was far more tolerable, but still bad.

Thanks man, currently getting the balance checked like you said! Will keep you updated!

So two things:

1. Turns out my balance was a little off
2. I have two bad wheels, so I guess it’s time to invest in some new methods! Have worn these out offroading!
I live in the middle east so we’re always out offroading.

Posting some pictures of my truck.

Thanks guys! Appreciate all the help

So... what I hear you saying is that you’re a bit of an over-achiever. ;-)

Glad you got it diagnosed. Good luck on the fix !

Yup, I had the exact same issue. I took it to a Ford dealer who told me the rires has to be road force balanced. They did it and returned the truck. I still had the issue. Desparate, I went to another Ford dealership. When the shop Forman called me he asked me to confirm that I just had the tires road force balanced. I confirmed. He replied "what are they blind? Not only was there not one tire close to balanced, they were all off in different ways.." On the way home it was smooth as butter from 30 to 90 mph.

another thought, I'm not being a jerk, just throwing this out there. Have you parked like an ******* recently? SOME people carry those tire weights that peel and stick for just such a thing. Just a passing thought. Of course, I would Never think of doing such a thing.

Hi,

Had this issue last year for a year on my 2012 supercab.

Ford checked all the suspension that was OK.

I went back to BF Goodrich. Force balanced at 3 different places and during this period 6 tyres were found not to be acceptable.

I eventually got 4 good tyres on it. Bliss.

What a pain. I even had my Fox shocks services at great expenses.
