I don't know if this is the info you meant for me to obtain jstmoto, but when I tried what it is I think your telling me to try. When I feather the pedal at all speeds the shaking starts at 44mph, If i then release the gas obviously it stops shaking and if I hit the gas when it starts shaking it'll stop until I get to a cruizing speed once again and maintain it. It does not do it at all when accelerating fast enough it's only when you accelerate slowly and when you get to a speed between 44-60 and maintain it.

 

Has anyone ever heard of pierce fuel pump & module or tre-379 fuel pump? Are they any good?

 

My rig shakes at 50mph as long as i keep it above or below 50 it doesnt i did however notice that my tires do not have balance weights on them could my tires not being balanced cause this problem???

 

Yes. There are other methods of balancing tires though.... or, they may just have not put weights on the outside of the rims..... Take 'em in and have 'em balanced, see what happens.

 

i have the same thing happening to my 95 ram,what fixed it?

 

Try getting your tires balanced. Then check for play in the wheel bearings if the tires balance out just fine.

 

My truck had a bounce at all speeds above 35. Got the tires rebalanced (and rebalanced, lol) and it has since mostly gone away. I still have the 45mph bounce, but that seems to be pretty common on Dodge 4x4's.

 

It does? Never noticed it before... Girly TT had some good advice... Try that and see what happens

 

Or at least that's what I've read. I do think I have some slight hub issues though, then again, it's had it since I bought it and it hasn't gotten worse.

 

How are your shocks?
