hmmmm i put the leaf spring helpers from autozone and that damn near got rid of wheel hop at take off. but idk about ur prollem at 70

 

It feel like its coming from the front end. :ugh:

 

wow man im completely stumped!!!!!

 

Broken belt in the tire? Put a different 22" tire on in place of the bumpy one and see what happens.

 

Generally, if you have a broken belt its visible from the sidewall isn't it? I do have a 3/4 drop on but that shouldn't make a diff between the 15''s and 22''s should it. I realize the diff in sidewall but if it was a suspension issue, it should do it regardless?

 

yah if its suspension issue it shouldn't matter what wheels u have.....put that rim in back and take one of the back ones and put it up front,.....see what happens

 

swap ur front 22s to the back and back to front and u can tell if its coming from the front or the 22s in the back

 

So. . .does it sound like a balance issue? :ugh:

 

it could be man

 

i had that problem.....if you think you have a balance problem get the lug centric balances, my shit was off!

 

Seems pretty logical....

Heavy wheels with very little sidewall give + weak springs/shocks = bouncy.

 

check your tires.... one on the 2's could be seperated and that'll cause wheel hop at a certain speed or can increase according to speed.... i had a cooper cobra sperate on my old ford.... it bounced right at 45 for awhile then started doing it constantly and turned out i just needed a tire...

 

was gonna say the same thing,only on a Chevy Astro van......try swaping the rears to the front and vice versa and see if the hope goes to the rear.....Rob..

 

I agree with Slo86GT. I'm guessing your 22" wheel and tire weighs more than the 15" stockers, and the tire sidewall is MUCH shorter. So, two things are happening.
1. The shorter sidewall is transmitting more of the bump into the suspension compared to the tall stock tire.
2. Your tire is a mass, on the end of a spring, which requires a damper (shock) to damp out the oscillations in the system. If you increase the mass on the end of the spring, you need more damping force to resist the movements.

So, I suspect that your current shocks are too weak to damp the movements of the heavier tires/wheels, given the larger inputs to the suspension system.

I'm ordering a set of Belltechs' lowering strut kit. Should take care of the problem :thumbup:

 

You should still rotate the tires to make sure one of the belts hasn't broken or that you have an issue with the wheel and/or tire. Don't want to find that out the hard way. Broken belts are not ALWAYS visible on the sidewall or tread, sometimes it's a real PITA to find until it just lets go.

 

yea i agree just did two tires yesterday and the drivers side was bad and they never noticed the buldge in the tread lol

 

Once you get the new shocks on you should also get the truck aligned with the 22's on it if you hadn't already.

 

and maybe even rear shocks tooooo

 

Soooo...wtf?

 

mine reacts almost the same way when i have the 20's on compared to my stock 15's, but it is much less pronounced with the 15's

i have new upper balljoints, lowers arent that old with bilstein shocks and a bag and it happens at any height. only thing i'm thinking it could be is tierods, but i havent checked mine

and its bumpsteer, not wheel hop

 

Bump steer? He didn't mention anything about the truck traveling left or right after hitting the bump. I won't rule it out though. You probably just need new shocks up front. Have them check your tie rods to see if each one is pointing toward your instant center and to make sure their lengths are relative to the inner mounts of both upper and lower arms and both ball joints.
