Guys (and Leann), it might be me -- but at around 80-85 mph it feels like the truck is straining. At first i thought it was because of the cold weather or just aerodynamics, so i didn't push the truck that much. But then we had great weather this week (like 60's) and i really got on it. It felt like something was vibrating against the gas pedal as the truck accelerated over 80.....not a clanking, just a constant tapping...around 100 it really feels like the things going to break...am i just being a wuss or should i be concerned. With the tri state thing coming up i know i'll be running at WOT and DON'T want to be carrying my engine home in a cardboard box!!

My GF has an infiniti g35 which is a completely different car, but at 80 it feels like it's going 20....know what i mean??!!!

 

Typical case of a CT guy fabricating a problem to cover his lose to the NY boyz



PS sorry do not have a clue what it could be

 

If it grows with speed? Then more that likely it's an imbalanced tire, driveshaft, tranny tailshaft bearing, u-joint, or somewhat unlikely a bent axle or brake rotor. These are about the only things rotating at constantly increasing speeds.

First drive it at speed and carefully put it in neutral & kill the motor. If it DOESN'T change at all then 1st rotate the tires & re-drive/test. Stiil no go? Then go looking deeper. 2nd the driveshaft balance, 3rd the u-joints, 4th the tailshaft bushing (I had one do something like your describing on a stang about 10 years ago. Drove me nuts trying to figure out what it was)

If it does change then you'll know to look into the motor/tranny.

thanks for the reply rich...i actually haven't rotated the tires yet....11k ....so i guess that should be the first order of business.

and halflife i guess we'll have to see how you NY guys can handle my beast in the "tristate challenge"..... and if Rob02 is listening...i don't want any part of you and your drugged beast (NO2).....lol..

this def. gives me a reason to drop the cash for a full exhaust.....
