hey guys when im cruising at around 80km-90km my truck has a shake nothing crazy like when my hanger bearing had to be replaced but i can feel it in the seat.

any ideas? im thinking u joints?

an unbalanced driveshaft can do it so can u joints as long as youve eliminated the usual front end suspects and tires

I had the same thing with my truck and went crazy trying to figure it out. Wheels, Tires, axles , drive shaft. I had a lot of little gremlins in there. My seat would shake left to right at about 50 to 55. After beating my brains out on this the only thing I had not changed was the brake brums. To my amazment it got rid of about 60 percent of it. I still had a little tire issue and a little drive shaft issue. But finding the biggest problem helped to find the smaller problem. There may be more than one thing causing your shake. Just keep plugging at it . You will figgure it out.

Just a thought - transmission/motor mounts.

Have you checked the steering stabilizer?

what do you mean when you say that i think of the smaller shocks on 4*4's
mines 2WD.

76/85 Truck · 01-19-2012, 09:30 PM

The steering stabilizer is a horizontally mounted "shock absorber" on the drivers side in front of the axle. I think 2wd's had them...?

What about spring bushings they will give a slight shake or vibration if they are wore out

cory d · 01-20-2012, 11:41 PM

i had vibration at the same speed as you (50 mph). after flipping the axle it corrected the angles and went away. you could check the pinion angles
