A little help with shudder....

I have this shudder at 45-50 and Ive been trying to pin point it for awhile, but am at a loss...
Part of me thinks its the tires but I also suspect it to be the drive line, bc it was there when I had my stock tires...

I just checked my driveline and u-joints, and when I twist it it feels sloppy, It feels like I have a 1/4" of play either way before I spin the whole shaft....
That cant be normal right?

 

Did you just lift it? Have tires balanced if it presist do a carrier drop or a shim.

Mu drive shaft has a little play in it, I think its normal.


Dont forget to grease your u joints!

 

I have the same thing at the same speed .

Still trying to figure it out , I'm hoping it's tires but it was there but not as pronounced before I lifted .

 

^^ Exactly... Ive tryed both CB Drop and shims and both didnt cure it.
Im ganna try tires next, bc I need them. If that doesnt cure it, it has to be my ujoints...

 

I hope it's not your u-joints cause Toyota doesn't sell the 4x4 u-joint as a seperate part, you have to replace the whole shaft. You could carry it to a driveline shop and get aftermarket u-joints fitted though.

 

What I am going to suggest helped out another fellow member with the same issues.

Look at the weights on your wheel, do you have 1 set of weights either in the middle of the rim or right behind the spokes OR do you have 2 sets of weights placed on the rim? A lot of the time with aftermarket wheels that use tape weights the tire shops will use just one set of weights (static) when most factory wheels use dynamic (weights on both sides of the rim). I would suggest going back to the tire store and asking them to do a dynamic tire balance with the correct hub adaptor on the balance machine.

Hope that helps!

 

^Thanks! I will be getting new tires soon so I will have them road force balance them and see if that helps...

If not, its going to toyota and hopefully they will fix the problem.... It should be covered under the drivetrain warrenty right?

I almost want to go put my shims back in to see if it makes a difference....
What you think?

 

Might as well put the shims back on and see what happens.

I just lifted mine and used the axle shims and carrier bearing drop and no vibes but I have a barely noticeable shudder when accelerating from a stop (only under 10mph). Doesn't bother me...and anyone who has never driven my truck before the lift probably wouldn't notice it.

I don't know if our different cab styles make a difference in this situation though.

 

Im pretty sure its my Tires. There cheap, old, crappy tires.
Its been hard to save for new tires, but Im hoping to get tires this month sometime...
