New Lift Weird noise

SouthTxMega · 10-30-2009, 01:17 AM

Hello all, recently had a shop install a 6" bds short arm lift on my truck. Is it normal to hear a buzzing sound? i normally get the sound going greater then 45mph and as speed increases so does the sound. Is it just wind noise?

any help would be great, I post pics a little later.

Where was the lift done?

I currently have 35" tires Dynapro Hankook MT on the stock wheel. I had these tires for a few months since Feb. The lift was done locally. My schedule/school would not allow time off to go out of town to have the lift done. I should specify that i dont hear any noise will driving less then 40 mph. I took the truck on the highway and notice that buzzing/winding noise that i think is coming from the drivetrain area. The truck will increase speed no problem but the sound is of concern to me. took my old man for a ride and he feels that it might be the tires. Prior to the lift i could hear the tire at any speeds. hope you all understand what i am trying to say.
thanks.

Gotta be a driveline issue. Is there any vibration or just noise? Grease your u joints, maybe has somthing to do with changing the pinion angle. I don't know, sure it's not the tires though right?

no vibration, just noise. I will see if could get someone to help ujoints and pinion angle. not sure about the tires theres always a possibility. Went back to the shop and was told that its normal to hear that sound. Their explanation was since my truck was sitting lower i was unable to hear the tires, now that its lifted i will hear them more. I will driving my truck a bit more to better describe it.

thanks everybody.

ok so you are telling me that the guy told you that when you where closer to te tire you couldn't hear it but now that you are further away it's more pronounced!!! Hahahaha! That guy is an idiot! You need to angle your caster back so that your front drive line is more in line with your TC.

driveline... had the same problem took the front driveline off no noise put it back on. noise

Clock the case 10 degrees . Try taking the shaft out first and see what she does. Is the case in a gasser further forward? If so this makes your angles all the worse.

Its the rear carrier bearing. You need to get the shim kit to lower it. (2 steel plates about 2" wide, 1/4" thick, 6" long.

If you don't do it quickly, you will ruin the carrier bearing.
