Front End Vibrations at 55mph - 2012 CrewMax with 28,000 Miles

Ok Tundra Techs here's the low down:

When accelerating vibrations start at about 50mph then worsens at 55mph. The truck also pulls hard to the right when I let the steering wheel go. I feel like the vibration is coming from the front passenger side. I did take a look at that side and noticed that there is a build up of oily substance on the front passenger side strut. Could this be the problem?

Questions you might ask:
Tire Flat spots? Rotated & Balanced? not likely, I just had the tires rotated and balanced and the vibration still exist on that same front passenger side. Pretty severe when the dash board flexes up and down.

I barely drive the beast. FYI, 2012 Tundra CrewMax and has 28K miles and fresh off the 5 yr/60k warranty. (of course) Could any of you Tundra Techs give me some suggestions as to what might be the problem? I'm pretty disappointed that I'm even seeking help being that this truck is practically brand new.

 

Sorry to hear that, hopefully you get it figured out.

 

What is the buildup of oily substance on the shock? Blown shock? Leaking CV boot? Road force balanced or just a regular balance on the tires. Although alignments shouldnt affect vibrations, it also shows if any ball joints, tie rod ends are loose...gotten an alignment lately? Checked your CV axle?
Are all suspension and driveline parts in spec?

 

Nick T, this is the response I wanted. I appreciate your help here. Will delve more deep into this and investigate the above suggestions. Cheers!

 

I had a bent rim once that would vibrate between a certain speed range. The fact that you mentioned a speed range makes me think it could be a bent rim. very easy to spot at a tire shop but they usually do not check it unless you tell them to. At least that was my experience. Does the car pop or crack when you are turning? Does it feel weird or make out of the ordinary sounds when you turn or go over a bump / hole ?

Is your suspension stock? If not, what are the modifications?
Are the rims and tires factory original? If not, what are you running?
