Hi!
My 1993 Dolphin has been giving me some vibration problems. I've had the tires balanced up the wazoo, including the "road force balance" which is supposed to be something special, and did seem to help. Just had the drive shaft balanced a few days ago, which also helped. The test drive after showed improvement, but a good assessment is difficult to make, as I live in Illinois and there are no good roads here. :( It rides pretty smooth up to about 65 and then starts a general vibration. Doesn't feel like it's up front, as I don't feel it much in the steering. It gets worse at 70. I usually travel at 60 to 65, so you might say, "so what's the problem?" To me, it still indicates that something is wrong & needs fixing.
I've been told by a couple of mechanics, who might be making this up, that since it's a light truck with a heavy load, to expect vibration
So, what's normal? I feel bumps & imperfections in the road so much more than in a car or in my 4Runner. I assume that's normal. But is vibration at the higher speeds normal? A mechanic who's had much experience with the truck, but not with a house on it, says it should ride smooth.
Any opinions, info, and ideas will be much appreciated. Thanks.
Mike
