Knocking coming from the rear.. esp when people are in

Post by TeJero »

Hi everyone
I do apologize that I'm asking a question on my first post, but I'm hoping that someone can shed some light.. and help me out

I don't actaully own a vauxhall :meh: :? But my housemate does, so here goes

She owns a 1.0 envoy - w reg, for the mot last in jan she had the centre pipe replaced (along with quite alot of other things) anyways it passed its mot, (not much on advisories just simple things, most of them I sorted out for her so we could limit that in the noise)
Anyways she said when going over a bump she has some noioses, sounds from the exhaust?, so I have a look underneath for her and the centre pip that the garage replaced doesnt look tight, anyways noticed the backbox looked new but was held together by cable ties, nice... replaced them with the correct bushes, and tightened it up, it desont "knock" now when going over a bump but she says when she has people in the back the "knocking of exhaust" noise is still there and its very loud, people look at her funny,
I've checked everything else on the rear wheels, suspension, bushes, top mounts etc, tried the front as well, the backbox is FT and i cannot move it now (before you could move the tip and it would hit the bumper, now it doesn't) the centre pipe is there meant to be a bracket after the cat? (i ask as my ford and nissan have these, and hers doesn't)

Anyways Shes (my housemate not the car lol) getting annoyed, its been to the garage etc they say its fine, one said wheel bearing slight play which was a advisory but I sorted that out for her and it didn't make a difference. And shes thinking of scrapping it which to me is pointless as apart from this its fine, nice colour too (blue) and has a bit spent on it already

I did notice when i bounced tested the rear suspension, it made a noise but it stopped after bouncing down and no leaks etc there, does anyone know what it may be or any info would be grand

many thanks

could be the exhaust knocking on there rear axel, quite common on corsa's with no genuine vauxhall parts. try rotating the exhaust abit to giv it abit more clearence.
OFFICAL DVLA DATA:
1414 - corsa gsi's on the road in 2008.
735 - corsa gsi's currently on the road and 436 SORN
Basicly you would have to be a right tw*t to break one for parts :rant:

Thanks to everyone for an awsome weekend at pvs!
