I recently asked a question on this board about my Suburban having an oscilating vibration starting at about 67 m.p.h.. I feel it in my feet and my seat. I have been trying to pay more attention to it and listen a little closer and it appears that the oscilating vibration quickens under accelleration. When Im ascending an incline such as an overpass the r.p.m.'s pick up to maintain a speed of 73 m.p.h.. When the r.p.m.'s pick up the vibration quickens. Once I reach the crest of the incline the r.p.m.'s return to where they were and the vibration returns or slows to where it was. What do you guys think?
id say check for tighness of bearings like the pinoin bearing, i dont know if suberbans have 2 piece driveshafts, but, id say check for bearing tightness such as the pinion, my 10 bolt pinoin bearings got chewed up by steel filieings from my screwed up gov-loc [img]images/graemlins/mad.gif[/img].
I'm not trying to get on anyone's case about anything, but you would be better off posting on your old post. People will then see what other people have already said, rather than repeating the same things. Also maybe someone's other post might spark a thought for someone else, in the end if the subject is the exact same thing, you'll be better off using the same thread.
