I have a 1990 Ford F150 4x4 on 36 inch super swampers and i have a very bad wobble and ive replaced the wheel bearings inner and outer and replaced all balljoints and also the radius arm bushings and new superwinch hubs and tightened up the drop down pitman arm. Front tires are balanced to.. when i get up to about 35 mph the front end will start hoppin and going crazy feels like its gonna come apart. but if i punch it itll go through the wobble but as soon as i let off it comes back. i put 31's on it and it didnt wobble or nothing except one time after hard wheelin drove it all the way home super slow let it sit for a little bit and it just went away again.. do you think this could be pivot bushings or u joints any help would be appreciated.

 

who balanced the tires for you and how long has it been since they were balanced? bigger tires are harder to balance (though 36"s should be too much of an issue) and some shops half-*** it. hell some shops just half-*** everything.

 

a guy my father knows balanced them for me at the shop he works at so im sure he did it right and there probably hasnt been more than 10 to 20 miles put on them since they got balanced

 

I had the same thing happen to my 95 4x4. It went into a death wobble one day and scared the water out of me. It felt like the wheels were coming off. I have 33" mud tires with a 3" lift. I replaced the front steering stabilizer shock with a rancho unit ($70),that solved that problem,old shock was apparently bad. Everything I have been told and seen in catalogs has said that anything over 33" tires requires a dual shock stabilizer setup. These kits are readily available everywhere and are not that hard to install. With 36" swampers this is the way to go. Good luck.

 

Im planning on getting a dual steering stabilizer but i wanna get the wobble fixed before i get it, i dont wanna just like mask the problem, because the truck used to be okay going down the road and then all the sudden after hitting the little bumps in the road the front end has gone crazy with those 36s.. but thanks for the advice

 

Did you have it aligned after the front end work?

 

I don't think in this case a dual stabilizer is masking the issue. I had the same issue on a dodge I had lifted on 37's. The stock equipment simply isnt designed to handle that size/weight of tire so all the things that use to be little bumps are now magnified by the mass of those tires.

 

no i havent had it aligned yet. And it could handle it before i hit those little bumps. it would roll just fine now every time i get up to 35 the front end feel like its hoppin up and down its more the whole truck shaking than the wheel. and when i back up or go foward i here like a loud clunk and ive done replaced the ball joints which is what i thought it was first.

 

if you feel it in the whole truck and not just the wheel its probably in the rear. Check your u joints

 

You hit a bump and now it feels like the WHOLE TRUCK is shaking rather than just an unbalanced tire? Sounds more like drive shaft to me. Maybe a weight came off. the clunking could be bad U-joints.

 

well i put 35 inch bf goodrich a/t on the front and it didnt fine and then all the sudden it did it once i stopped took off again and it didnt do it anymore. and does the front driveshaft spin all the time

 

the front driveshaft shouldn't spin unless the hubs are locked or the truck is in 4wd or both.

 

thats what i thought i dont know what it is maybe the pivoting bushings are bad imma check those next time im at the shop

 

rotate the tires and see if it goes away. If it does, suspect a separating tire or bent wheel. Is your truck a long bed or short bed? Check the carrier bearing (if it has one) to be sure it isn't letting the driveshaft move around. How old are the shocks? Worn shocks will allow the springs to oscillate after a bump and allow the tires to bounce.

 

Agreed, too much tire for small light duty components.
