Shudder in 4runner

[damo4runner]

I have a shudder at low to slow speeds, normally just after take off (5Kph)when taking off and getting into 2nd (upto 30kph max) but it also happens when I am slowing down to make a corner or taffic light (using engine to brake this rules out disk warp I think), I did have a left rear axle seal that needed replacing and this was done at the same time as the clutch and rear main seal I think they would have cleaned any oil leaking onto the rear drum if that could be causing the problem. I don't think that it is clutch slip the new clutch only went in 3 weeks ago and the flywheel was machined the shudder was there before and the rear diff was rebuilt only last week, the shudder is still there could it be the fact that my tailshaft is out of phase? The shudder also seems to go if I put my foot on the clutch to the floor whilst going though the corner (rolling) naturally I can't put the clutch to the floor when taking off. I know this sounds a bit vague but I am running out of ideas as to what it could be, any thoughts or suggestions would be greatly received.

Ps. I am by no means a mechanic but I will always have a go before paying someone else to do it.

Damo,
check your tail shaft uni's and the alignment of the yolk. when I redid my uni's I shoved it back in with the yolk 1 tooth out from original position (marked it all b4 removal) and had a vibration, I realigned the yolk and perfect.

Thanks I know that my tailshaft is out of phase and I am currently trying to get it off so that I can put it back in phase hopefully this will solve my problem but I am having trouble removing the tailshaft all the bolts are out but I still can't get it off........

does your 4runner have a centre bearing ont he rear shaft? on my 84 lux i had the same simptoms and it got worse to the poitn where if u took off there was a fair size clunking feeling and noise and it ended up being that the centre bearing had collapsed

[damo4runner]

thanks for the thought but my 4runner has no centre bearing, I've just been told to check if the diff oil that is in the rear is lsd oil or just normal this fixed a similar problem elsewhere, must call the mechanic 2morrow
