Need some help in diagnosing a vibration in the rear of my '83 Hilux.
The vibration seems to be worst at 95 - 110 km/hr, at that speed it is rattling the gear levers for the transfer cases.
At first i thought it had to be the rear tailshaft as it had single uni joints, so had a cv / cardan joint fitted and balanced. Then rotated the rear diff pinion to be 2 degrees lower than the tailshaft slope.
This seemed okay for a while but the vibration has come back?
Does the pinion need to be down 2 degrees with a wrap bar?
It has a v6, auto with dual cases
Could the cv joint have gone bad or using an ifs cv not allowed for enough operating angle?
What is the optimal operating angle for these cv's?
Cheers
Matt
