Front end vibration

[pauly47]

I've been trying to get rid of a front end vibration that has dogged me since replacing my worn out Revos and getting an alignment done on my 04 Seq. I ordered some Pirielli Scorpions from Tire rack and had them mounted on the Toyota rims from the same place that did an alignment. We had a vibration in front end and steering wheel shake and 60-65mph. Tire rack swapped out 2 tires thinking one was out of round but problem did not go away. I ordered 4 new Yokohamas mounted/balanced on rims from Tire Rack and the vibration is still there but not all the time. I can put the cruise on and its smooth and then I will feel a gradual build up of vibration that causes steering wheel to shake and then after a few miles, it dissipates and ride is smooth again. Any thoughts? It doesn't seem to be the tires as its not consistent.

Two things: #1 Did you get a print-out when the alignment was done? Tundra & Sequ. of the vintage of your SUV & my pickup are both bad about vibrations if the Caster, in particular, is not set at the upper positive limits of Toyota's specifications. #2 It sounds like it could also be a wheel balance problem, especially if you have the non-alloy OE wheels. To correct (or check for the possibility of) this problem, get thyself to a tire store with a road force balance machine AND AN OPERATOR WHO KNOWS HOW TO PROPERLY USE IT! Believe me, two 'technicans' that are HARD to find are an alignment man who both knows how to properly align the first generation Sequ. ot Tundra, INCLUDING setting caster and camber properly and will go the the slight extra bit of effort to actually do it right AND a tech who has been properly trained and understands how to road-force balance a tire on the wheel and who will go to the slight extra effort to do it right.
I feel for you. Been there...done that. Luckily I found a tech 40 miles from me who does a proper job of using the road-force machine, but I still go 325 miles for alignments. Thankfully, once right, these Tundra & Seq. vehicles stay in alignment, barring accident or horrible abuse by the driver(s).
