exhaust noise

[Lucasmax]

can anyone help me! i have a 1994 1.2 8v ls and the exhaust knocks on the back axle/handbrake cable. that doesnt bother me that much but after iv been driving for a bout an hr or so, when ever i go slow or stop at traffic lights ect theres a juddering sound but its not comin from the engine i dont think and it makes the whole car vibrate almost. does anyone know the reason for this? or what it is?


will i have to get a new exhaust?

[wilsonimrie]

check the exhuast is held on properly by the two rubber bushes that should connect onto the prongs comeing from the exhuast there should be another two prongs coming from the car too it could be this

Mine does this too, i think we just need new exhaust rubbers

I just got a new exhaust back box fitted it's really heavy compared to the old one and mine does this after about an hour. Try the new rubber exhaust mounts, you can get them off Ebay for about £3 or so. Should stop the problem if not check the exhaust is fitted correctly because sometimes they can loosen and end up blowing.

yeh im sure u will find either the rubbers are knackered..or try pushin the backbox onto the middle pipe as it can sometimes pull itself lose

i have a very old fashioned approach, it worked really well with a dash rattle i had a few months back........................ HIT IT WITH A HAMMER!!!!!! If that fails then i will try and think of something sensible for you like check it isn't blowing, seriously sometimes even the slightest gap or loose connector will make a wierd noise. Get it upp on ramps and run it to try and pin point the sound. Let me know how you get on

Get it upp on ramps and run it to try and pin point the sound

Washing up liquid can help there.

Have you checked your engine mounts?

enigine mounts the bit where the metal prongs are on the car?

[prawny12009]

your engine mounts are the rubber bushes that attatch the engine to the engine bay, you will have one on the left hand end of the engine (looking from front of car) one on the right attatched to the gear box, and one at the back of the engine sometimes one at front as well these are the ones that will cause trouble because although the ones either end hold the wieght of the engine the ones in front and behind stabalise it abd cushion all the driving loads,

if the engine mounts/stabilisers are worn then the engine can rock excessivly and causing the exhaust to move back and forth letting it knock against things, hope this helps clear things up for you.

all the rubber has been recently replaced (as in replaced in the last week)
