November 27, 20178 yr A mate has a Toyota Sport Rider. At about 3000 rpm in 5th the whole vehicle shakes. We thought it maybe Somchai over-inflating the tires but we checked and they are OK. Then we noticed if he lifts his foot off the go pedal, without reducing speed, the vibration stops. So it would appear not to be drive train related. Anyone else have or had a vibrating Sportrider?
November 27, 20178 yr Vibration on my auto truck roundabout 2000 rpm was tyre balance under or over was OK. Maybe a check on UJ as Trans said and a check on all 4 wheels and tyres for faults would be start.
November 27, 20178 yr Author The weird thing is that when the "drive" is taken away. IE foot off throttle it goes away.

November 27, 20178 yr 2 or 4 wheel drive? Almost sounds like a UJoint/carrier bearing on a 2 piece drive shaft..... Does it do it in every gear at 3,000 rpm or is it more speed related? Does it feel more like the vibration is in the front, body, or the steering wheel? Have the tires checked for possible ply/belt separation just in case..... Is there a noise along with the vibration?

November 27, 20178 yr Where is the OP/driver located? Might be good to know.... If in CM go to ProAuto & take a tech for a test drive to demonstrate.....

November 29, 20178 yr One time I dealt with a ride with the same prob, took the prop off and found nothing wrong with it, had a similar ride at hand so l took the prop off to try on the prob ride. Problem gone. Took the prop to a prop engineering place where they found it was out of balance, a weight had come off..Problem solved...

I had a British Leyland van and going along one day it vibrated at the back the nearside back wheel then came off and overtook me. It was put down to the early days of over-tightening at places with them electric torque guns. The wheel studs sheared off.

Ahhhhhhh, MG Midget, wire wheels, me a passenger, driving along, big vibes, then both rear wheels fell off at the same time... He had put the half shafts in the wrong sides so the knock-on nuts undid.. How embarrassing...
