Trying to narrow down an issue that has raised its head since the Clutch and flywheel were changed for new ones recently
Bit of background:
I've been getting a clunking sensation from the rear of the car as I pull away from a standstill with the car on some lock.
Doesnt really change depending on the amount of lock, it just occurs when the wheel is turned and you dont pull away straight, you get nothing at all when you pull away in a straight line.Once the car is moving a bit then the clunking goes away.
The car just went into my local garage to have the radiator replaced so I got them to have a check of things whilst they had it on the ramp as they suggested it could be a CV joint.
Turns out it isnt that and they reckon its something to do with the LSD. Also of note is that the clunking will almost always be there after the car has been reversed and is then moved forwards again (again with some lock on)The guy from the garage took the car out for a drive also and he thought it could be LSD related but didnt know enough about this particular car to advise any further.
I dont know if the diff has been changed over the years for an aftermarket one but when the gearbox and drive shafts had been taken out of the car for the clutch change etc the garage did suggest that the Diff looked like it could be different from standard
(when looking into the gearbox from the side).Now here are my thoughts:
I was wondering, as was the chap in the garage if the wrong gearbox oil had gone back into the gearbox.
If it wasn't right could this cause some nasty clunking sensations from the LSD? Guy in the garage said something about a clutch being in there and that perhaps it wasnt working properly due to incorrect lubrication? Does that sound correct?Another thought of mine is could the driveshafts be the problem? The garage said it all looks ok however they didnt know if the driveshafts had to be lined up in some way to make sure the LSD worked properly.
This may not actually make any difference but perhaps someone could advise who knows about LSD's in the MR2?The reason i think its the lsd buy the way is the back nearside rear tyre seems to catch and release as you pull away.
The garage also suggested this was what is happening, almost as if the car isnt being allowed to spin the outside wheel up at a different speed to the inside wheel as the car is making the turn. If this is the case then i guess this would account for why the sensation only shows itself when the car pulls away with some lock on?Also you seem to notice the problem more when pulling away slowly whilst making the turn.
If the car is given some proper grunt whilst pulling away then the sensation isnt as noticeable/isnt noticeable. I wondered if this was because the wheels are just being forced to turn at the same rate as the power is applied in bigger quantities through the LSD and thus you simply dont experience it as the lsd is forced into action? Anyway enough gasing, would people please make any sugestions they might have on this.
Much appreciated
