hi everyone!
well as some of you know i bought my first t4r lastnight. i love it i needs a couple of things but nothing major. but the most annoying one was when i was on the highway it has a consistent vibration kind of like if you had 2 12 in bass speakers playing one low bass note at one freq. it would change speed with the speed of the car. it still did it in neutral and it would it almost seems like something out of ballance. didint sound like a tire or feel like one this was shaking the whole runner. like if i had bass in the trunk. any ideas i really havnt checked any rotating parts yet. i definately think its part of the wheels axles or diffs. something that rotates with the truck while moving so that rules out the tranny right? it shifts smooth through the gears and the motor is peppy.

 

here is a pic

 

Could be a universal joint going out.

 

ill replace both today just to be safe.

 

Easy way to check is to mark your driveshaft and remove it (8 bolts, 4 on each end) and drive in 4 WD (essentially, front wheel drive). No vibration=U-joints, most likely.

Put the driveshaft back in, lining it up with your marks to make sure it goes back in in sync.

 

Smart man! ill try it this week end.

 

Been there, done that. Had to drive like that to go get new U-joints.

 

i took a quick look at lunch break and it looks like the drive shaft has a dent in it.

 

What did you end up doing?
