I finally got some miles on my Traction Bars this weekend and I have a question for you long time users.

Driving down the road, highway or back road, Cruising along, If I get into it Hard the rear end squats and I feel a vibration in the rear, Like a driveshaft Vibe. If I Ease in to it, that vibration isnt there.

Have yall ran into this problem? Any thoughts on this issue?

Thanks!
Rick

 

No Thoughts Huh?

Rick

 

pinion bearing or U-joints??

 

x2 on pinion or u joints
shake it down

 

Maybe Driveline Inclination.

Pinion angle changes drastically when the rear end squats, it should ideally should be no more than 3*

How hard are you gettin on it and what type of superglue tires are you running????

Last time I saw my truck squat I had darn near 2 tons of pavers in the back.
And when I throw milage out the window and find the floor with the skinny pedal my reear end makes noise..and smoke......but I don't get anywhere fast except to the tire store.

I had a '69 Mach1 that used to squat off the line but I had serious street meat on the rear and a much closer to 50/50 weight distribution.

 

Not squating like its loaded, but you know the feelin, hammer on the skinny and the rear end pulls down and go.

What I am wondering is, is the traction bars sending the vibrations from the axle up to the frame of the truck where I'm feelin it inside now vs when no bars and you cant feel it.
Thanks
Rick

 

Do you run preload on your bars?

 

my bet is ujoint/ driveline angles.

 

No sir, I can grab the bar and twist it by hand either direction.
