Hi,
My 80 has developed a vibration which is driving me crazy so am looking for some ideas.
It is a shudder upon acceleraion but not from a standing start. Its almost like a rumble that shakes the car
Once it gets to about 40km/h it feels like a shudder and if I back off the throttle the shudder is still there but fades away once speed reduces.
What I have done so far is,
Checked and repacked all wheel bearings, there was a tiny amount of play in the front ones and one rear however the bearing surfaces (both cup & race) were perfect so cleaned,, repacked and adjusted.
Checked and adjusted handbrake
Replaced both uni joints on rear tailshaft (transfer end uni had a minute bit of play, had been meaning to change for a while)
Checked front shaft, uni's appear fine (no play) - greased for good measure
Tyres are balanced fine so no probs there. No flat spots or anything (less than 1 year old)
front discs are in need of replacing however the shudder doesnt get worse if I apply brakes
Confirmed that none of the brake calipers are sticking
removed rear tailshaft and locked centre diff & took for drive........still a shudder
All suspension bushes are fine, shocks great and no broken springs
Im going to remove the front tailshaft tomorrow and try a drive as rear wheel drive.
Note, the shudder just appeared out of nowhere
Ive only ever had a uni joint fail immediately so want to ask if they can start to create vibrations and yet still show no signs of play?
Im at wits end so hoping someone might have some ideas?
thanks
rob
