Help needed

Hello everyone... I need some of your expert advice

I have a 1987 90 turbo diesel with 149,000 miles on the clock. Yesterday and today it has developed a major vibration. What is causing it?

• The vibration occurs at speeds above 35mph and fairly quickly reaches its maximum and stays that way at all speeds
• The vibrations occurs in any gear
• When I change gear or let off the throttle the vibration stops to return as soon as the vehicle is under load.
• I have checked the prop shaft joints and they seem ok
• I have run the vehicle for a short while with diff lock and the vibration is similar.
• I ran the vehicle in low ratio in all gears and there was no vibration at all. I only went up to about 30mph.

I hope this gives you enough information to tell me what it is.

Thanks

funny enough we don't have magical powers, I'd suggest you use some brains(if you have any) and jack the ****ing thing up.
I'd start looking for propshaft joint ****ed first.
:welcome2:
or transfer box issue

  Engine vibration or steering vibe?

• I have run the vehicle for a short while in four wheel drive and the vibration is similar.

  errmm 90 is permanent 4wd. so I'm assuming yu mean yu engaged difflock??

  So it's speed related which seems to point to bushes/bearings/props

I hope this gives you enough information to tell me what it is.
