Anyone notice a noise difference after lift?

just installed my 5100 up front and aal in the back and it seems like everytime i let off the gas it sounds like im in a damn wind tunnel. if it is normal then i can live with it just wana see if anyone else has this issue or not

 

Did you change tires too ?

 

still the stock tires

 

creaky leafs to be sure

 

not sure what u mean

 

well yeah it sounds like your in a wind tunnel you effed with the aerodynamics so now the truck has to punch a bigger whole through air to get going. if it bothers you just dynamat your truck or go my route and get an exhaust

 

OP you have a regular cab don't you?

If so welcome to the club. Shims may or may not help. Most times it will just make the sound happen at higher or lower speeds.

If you don't like the noise, shims may work or put the rear of the truck back where it was height wise, as it's the driveline angle that makes the noise.

For example you can put hundreds of pounds of weight in the bed, drive around and if you put enough weight in the bed, the noise will go away.

At first, I had 1.25" lift in the back and the noise would go away once the truck slowed down to about 50 mph. Now I'm about 3" of lift (via springs only now) and the noise goes all the way down to about 35 MPH and that's with shims.

If I had it to do all over, I would have left the back of my truck stock and just got coilovers for the front and stuck with 265's.

 

Yea mine starts about 40mph but just when i let off the gas. I can deal with it just at first had me worried thatbi might of effed up somewhere. I have gotten use to it now.
