THE noise

[Jarl]

I'll say hi first, I'm new here and on my second 80' series. First and 94 petrol and now my 1990 diesel 4.2 turbo and 530000ks but playing strong still.

I've developed a noise. When travelling at about 50 ks or up a hill I get a significant vibration and deep grumbling drone. As soon as I take my foot of the pedal it's gone. It started as only making the noise when turning left corners and climbing hills but now can even do it on flat straights. Sound concerning? Everything underneath looks ok no obvious major leaks. Any help welcome
Thanks

Are these vibrations happening on your 80 series or on a 95 and older Toyota pickup/4Runner?
