Shaking Problem Solved
Posted 07-17-2009 at 01:18 PM by jefhundra
All,
I am new to this site. I want to get more involved with the online Toyota community. I thought this would be some pretty good info to pass along.
My T100 began to shake at about 130k miles. Nobody could figure out the problem. Very noticible at high speeds (60-70 mph). 3 sets of tires and one set of wheels all from Discount Tire. No dice. They said the tires and wheels were fine (after several trips back to the store for rebalancing, etc.) I moved on from there to talk to licensed mechanics as that was enough for me. Suggestion by a mechanic to inspect the bearings turned out to be correct as the bearings needed to be tightened. That took the wobble-shaking out, but still had shaking. Suggestion by a friend to have my u-joints replaced also turned out to be correct as they were rusted and had not been greased. In the past, anytime I suggested routine maintenance include lubrication of the front end or anything else it was stated that the parts were a sealed system and did not require greasing. Not true as the u-joints have Zirc fittings (if you bother to crawl under and look). Further, the carrier bearing on the rear shaft was shot. I found myself replacing the rear shaft as it is two parts splined together and could not be repaired. Things improved after this was done. I also asked the mechanic to check the tires (high speed and road forced). After this was performed, the mechanic stated that he basically never saw such a poor balancing job. Also, that the tires were questionable. I had him balance and put the tires from my Tundra on the T100 with the old stock wheels and holy cow the shaking was gone!
Bearings, drive shaft & joints, and bad or incomaptible tires. Not to mention someone who knows what he is doing. It pays to find a good mechanic (I think we have all heard that one). The truck now has 170k miles on it and I kept it though all this crazyness because I love the darn thing.
If anyone else out there has had a similar experience it would be nice to hear from you. If any of this info helps you, please let me know as well.
