Vibration at 55 mph
Has anyone ever had a gearbox (LT 77)vibrate at a given speed.
My Cobra has developed an unusual vibration, but only at 55 mph, no other speed.
Wheel bearings are ok. Feels like it's coming from under my bottom when sat in seat.
I have greased the UJ'S on the prop. But not taken out to physically check if stiff.
Box works fine,changes gear easily, I have just refilled with correct oil.
May gland get rear wheels balanced just to rule it out.
I guess I just need to rule one thing out after another which will hopefully leave the culprit.
Thanks Mark.

Are your UJ's set up correctly.
If in phase they can cause this problem.
Have a read on threads like this

Or
You could have a tyre out of round, flat spot from sitting for a long period or delaminating after hitting a curb / pothole etc.
