front belt wobble and vibrating noise!

im having a few problems with my 1995 N/A SZ/R supra, so was lookin for advice please. 70000miles.

 

for the past month ive been getitng a vibrating noise from the front of the engine and diagnosed the front aux belt tensioner pulley, so i replaced the auxillary belt tensioner pulley today as the bearings had become very noisey. common ive heard.

 

So that small ticking noise has gone but the tensioner unit itself seems to vibrates loads when at about 5000rpm upwards and so i think thats createing a horrible thumping noise. is this a common problem for the unit to fail?

 

is there anything else to fail which would cause something to become inbalanced? balance shafts etc?

 

crankpulley is fine, and powersteering pulley has normal wobble at idle, so its gotta be tensioner right??

 

please help as its annoying me really badly.

thanks in advance

well when i had the belt off i physically checked it and when i was reving the car it was smooth as a nut. ive done a bit of research on here and i see its a common problem which is not good really, but im 95% sure mines ok!

i've heard that but the belt looks like it been on there a while and it never did it when i first got it, so its something that had deteriated over time and usage. still think tensioner is on its way out but should be ok.

tbh i think the problem has been cured by changing the pulley as it doesnt seem to do it anymore and seems alot smoother. so fingers crossed! i can now start learning to drift it.
