hey guys ive got a vs clubby and im getting a knock sound coming from the rear does it when i back off n on the accelerator and also when im slowing down the knock seems louder when the cars cold does anyone know wat the cause of this mite be i had the car the the hoist and turned the tail shaft there was free play in the shaft it was making like a knock sound when i turned it left to rite i heard all commodores came out like this even the new ones they call it wiplash in the diff is dat true or bull**** wat do u guys think my issue is
i hope so dat would be good also if its the uni is there anything else i should changed can i get stronger uni joints?
you can go a better quality unijoint though the one thats on it no doubt has been there for the life of the car, Its not uncommon for them to wear out after the years. I think the last one I used on my old VN was TOYO brand (was only a cheepie)
so go geniune ok then sweet ive taken the car 2 my mechanic and he said my diff is on its way?? im going for a 2nd opinion n c how i go
your diff will make a grinding sound if thats the case. but to be sure... have another listen when you turn the tailshaft and if the sounds in the diff then thats where the problem is
sounds like the prob im having with my vr except the grinding/clunking comes after 10-15 mins of driving. mechanic said he couldnt find the prob. :S
i have the same problem, when i slow down as it changes down it makes a lil cluk sound- maybe diff oil as well? cos the seal where the uni is on mine leaks oil abit, gotta get that fixed asap...
changing the oil may help to quieten the sound but its not a solution to the problem. You can get a second hand diff from the wreckers cheaper than it would be to rebuild the original though if the mechanic quotes you a reasonable price go for it
my clunk started after the first tyre change i had to do. after the spare was put on is when i first heard it, the first drive was really bad so i put it down to being the spare for some reason, maybe difference in diameter though i doubted it. When i took it to the kannick to have the tyre changed and full service i asked him to look at the diff, uni etc and to take it for a spin to try diagnose the prob. he said he couldnt put his finger on it and put in a really thick oil, he described it as having same consistency as treacle. Drove it home and all was sweet. 4 months later and another blowout. (these $200 a pop tyres are starting to **** me off). Got the car home and jacked it up, changed the tyre, dropped it, drove it and there it was, the clunk, right after changing the spare again. Took it back to Kev and he changed the tyre but when i drove home the clunk was still there as i was slowing down etc. (only thing different was that he didnt put the thick oil in). so, my spare wheel theory is out the window as the second time the tyre was changed to the original the sound was there right away. Mechanic says everything looks and feels ok, (would like to hoist and check for myself if i had the time). any ideas??
hey guys i just jacked up and had a proper look at it its i turned the wheels and jolted em rite n left quick and noticed a ching ching sound from the tailshaft uni joints also when i spin the wheels constentetly i heard a hissing hissing sound from the diff also i took it for a drive off the clutch to creep forward and knock reverse the same knock again on n off the accelerator still knocks and between shifts it knocks and the car bogs down once it happens does it 1st 2nd 3rd not 2 sure about 4th gear or 5th didnt hear anything its manuel 5speed does anyone know im getting it checked out soon
