Car is shuddering / vibrating over 50kph, when coasting or lightly accelerating. Still happens when I’m in neutral rolling. It goes away if I accelerate hard.
the centre bearing rubber seems to have a fair bit of play, can move it with my hand.
Has only happen since adding a canopy and drawers + a fridge in the back which in total is 220kg.
I’m not to sure if the centre bearing is bad.
Thanks

Yep, the center support bearing on the drive shaft can cause this issue. I would start with replacing it which is a common repair, so do you have after market rims? If so you may need centering rings so the rim stays true to the axle. If the center support bearing is bad but goes away while hard acceleration this is because the torque causes the shaft to be held to one side stopped the vibration. Please upload a short video in your response of the problem, so I can see what's going on. Ken
