Shudder at around 1800 revs, hilux 2.8d

Milamber
Remove your tail shaft and check the universals for play or binding. While they will stand a reasonable amount of play they really hate it with even the slightest binding. If that is the source of your shudder fix it quickly or you will also find yourself having to replace that rubber mounted centre bearing (I think the lux still has one of those??).

Could be a few things mate if you just had your suspension replaced
I have the same problem with car shuddering and it turns out that one of the wheels had egged it self
If the car had old tyres i would be having that checked

A shudder is too indescript. It needs to be test driven to give accurate opinion but having said that also check the centre bearing on the tail shaft. Also does it still do it with the clutch fully released with the car in neutral and the revs up? If if does then you can discount that as the shaft don't turn. If it does do it at a stand stiil in neutral while bringing the revs up then try it again with the clutch in. If it is evident in neutral with the clutch out but not evident with the clutch in then you can look at a gearbox problem and at a guess more likely to be lay-shaft related but do your checks first before you go jumping to conclusions and ripping out boxes, it may be something simple like a broken engine or gearbox mount or flogged centre bearing or universal joints the list goes on.. Good luck sunshine.

By chance when you had the suspension replaced did it also include a lift, if so excessive tailshaft angles probably compounded by a spongy centre Bearing , then look at unis

lowish revs when motor is starting to produce some reasonable torque, loading up drive train, had it in my lifted hilux for years.

Thanks for the replies everyone!

When the suspension was replaced (parabolics) it did recieve a lift of around 50mm. I was told that this would not be enough to adversely effect tailshaft angles, maybe it is after all as the shudder did not happen previous to the new suspension install.

The shudder does not happen when the engine is revved in neutral, only when driving. I will check out the uni-joints and centre bearing, hopefully that is all it is!

Thanks again
