42-50 mph shaking vibrating

[gcf330]

Maybe someone here knows what this is while driving between 42 and 50 the truck vibrates similar to an out of balance wheel but only at this speed any ideas?

maybe wheel bearings? make sure both your hubs are unlocked too

Drive shaft maybe? I had a vibration at 45-46 and only there and it turned out to be a u-joint.

Yeah its 2wd do no hubs lol but drive shaft could be sure enough its somewhere between 42 and 50 only for 2 or 3 mph didn't spend a lit of time trying to find it but gonna try tomorrow to pinpoint.

I had a bad tire do that. I swapped front to back and found the passenger side front to be bad.

It's very possible you threw a weight also.

I vote U-Joint as well. The last time my rear U-Joint went, it was between 40-52. Really easy to check, give that driveshaft a shake!

I vote for a u-joint going out.

i its the shat, jack it up hose clamps han help balance it... theres more info on it but its pretty easy

I had the same problem. After taking it in to a local front end shop it turned out to be a track bar bushing. Total cost of repair turned out to be $105.00, part was probably fifty cents...

check carrier bearing

Check shocks also. I had one sieze and cause same speed range vibe.

put it up on jack stands and start it up, this can tell you if its in the drive line or front end.

hold on, nobody asked the important question. where is the "shake"? in the steering wheel or in the seat? if it is in the steering wheel, it isnt a u joint. if u can feel it in your seat, it is the rear of the truck. steering wheel is front.

I feel it is in the steering wheel but i will try to fine tune on the way to work shortly. Thanks every one for the replies.
