Front suspension new parts are?


What was rebuilt of the rear end 4 months ago?


The "wobble/shake" > 60 mph started happening when compared to the above work? Before both of them? After front, after rear, after both?

 

Doing a simple plugs + wires tune-up will not solve a misfiring problem caused by a blown plenum. When your plenum gasket fails, the intake will fail to hold vacuum and you will then experience a loss of engine oil, misfires, and eventually a clogged catalytic converter which will further complicate the issue. Not every plenum gasket fails in the same way and each truck can exhibit different symptoms of the problem...a sure-fire way to check your plenum gasket is to remove the air cleaner and throttle body and take a flashlight and look down into your intake. If there is any oil at all that is pooling towards the back, your plenum gasket is done.

 

and the rear driveshaft u joints are new

 

the plenum gasket is okay there is no oil burning and there was no oil that i could see... the front suspesion has new ball joints, u joints, wheel bearing, a new track bar, new gear box, new tie rod ends, as for the rear i put new clutch packs in them after a garage messed up the rebuild, put new axle seals in, made sure axles were un damaged the ring and pinion is in good shape, drive shaft is balanced and have a new rear yoke, the shake starteds to happen after. the front suspension parts were replaced which was around April of this year. i hope i answered everyones questions,

 

You just hearing banging around over bumps? Or does the truck start shaking, and not stop once it starts? (till you stop, or at least, slow way down....)

If you are just getting a vibration above X speed, rotate your tires, and see if the vibration changes.

 

no banging, and it starts at 60 and will stop when I leave off but starts when I get on the gas again and ive already rotated the tires and it didn't do anything

 

How are your brakes? Does the pedal bounce around under your foot when you apply them?

 

brakes feel fine

 

That's gonna make it fun to find.....

That leaves bearings somewhere..... or, possibly a misfire that develops at higher RPM?

 

Also, consider having your wheels re-balanced and insist that they set the balancing machine so that it requires weights on both sides of the wheel to finely balance them. Lastly, you may have lost a wheel weight due to bumpy roads or improper wheel weigh installation.
