how long

[vq_statss]

can somone tell me why the touqre converter or harmonic balancer would vibrate the car badly and why the converter would do this can it be dangers and how long till it could fail....(years months) as my kids travelle alot in it ty

it won't be the converter, it'll be the flex plate the converter is bolted to, they can crack and come away from the crank. if it's vibrating badly i'd suggest getting it looked at if your not keen on getting under the car yourself and removing the inspection cover and having a good look at the converter/ converter to flex plate mounting bolts and flex plate itself for cracking/damage etc. you'll need a good lightsource as it can be difficult to see.

ok thanks heaps i was thinking of taking of the inspection plate to look but wanted info first ill look tmrw.......i dont know muck about autos (manauls yeh)if its not loose or cracked any ideas

Centre bearing/uni joints can have some vibrations. While your under the car looking at the tranny give the tail shaft a good riggle n see if it moves around at all.

Tape a 500 gram lead weight to the wheel of your bike and go for a ride. Even at medium speeds your bike will be nearly impossible to ride. How long it will take - impossible to tell. Could last months but then again the bearing might fubar next time you start the car. It all depends on how far out of balance things are and how good things were to begin with.

Sounds like you are on the right track. If it vibrates in park the problem will be in front of the transmission and most probably won't be the tail shaft.

took inspection plate off box checked flex plate and torqe converter not loose or cracked looks prety clean in there............harmonic balancer u think?

[fazz1977]

Harmonic balancers are pretty common issues in these cars. It will cause rough running and shaking depending on how bad the problem is. Not overly expensive to fix, or overly difficult either.

have a look at it, are there any cracks in it/ chucks missing, how bad is the vibration?

[immortality]

to check the harmonic balancer, do the visaul thing, then remove the serpentine belt and swing off the thing and see how much it moves, it shouldn't really move/deflect much at all

visualy it looks ok.....the vibration is bad (my 22 year old deisel landcruiser has less)1500rpm seems to hum in and out the vibration.nothing is touchin the engine.im 99% sure its not a miss.could it be in the engine .it runs smooth and quite heres the funny thing put hand on the engine u dont feel vibes at all.even throw the auto shifter.bad on steering wheel and u can feel it throw the car.graham

Could be the bush in the front of the trans, where the converter meets.
