christianmg Posted August 28, 2011 Posted August 28, 2011 Hey guys, just back from a month in Thailand and the car has been a complete headache! Firstly the battery was dead when I got back, but going by threads on here thats a common enough problem when left for a while. But now was just on way to see mates, too her to the motorway, everything was fine and when I hit above 65-70 even in 6th gear I was getting a REALLY LOUD vibrating sound coming from what seemed on the rear wheel area on passenger side. I can only discribe the sound as someone putting a ruler inside the spokes of a tyre and constant loud vibrating plastic'y sound. At first I thought it was coming from the boot, so I took my bags and jacket from the cargo net and put them in the passenger seat, pulled off the hard shoulder and as soon as I got into 5th gear it started up again. Pulled over again, checked inside and outside the car, even checked the rear numberplate to see if it was that that was vibrating ... everything solid, pulled away, kept below 60 for ages and no sound, put a bit more on the gas and it started up clear as day, like very loud! This cat and mouse game of pulling onto the hard shoulder lasted about another 20 miles before I turned home as wasnt too confident on the 110 mile journey. Any suggestions as Im going mad, everything seems solid under the car and inside the boot. Def coming from the mid rear to passanger rear side of the car, and very loud, but driving through town ... and nothing?? Quote
Karlp Posted August 28, 2011 Posted August 28, 2011 Have you taken your rear wheels off matey? Could be something on the pads or disc? Quote
christianmg Posted August 28, 2011 Author Posted August 28, 2011 Nope not since ive bought it!! I washed it today, and gave the alloys a clean, but the sponge is still intact so no debris in there, and I gave the wheels a shake on the moterway and they seem pretty solid and tight? Quote
magic84 Posted August 28, 2011 Posted August 28, 2011 sounds like a loose peice of bodywork, or has someone snaped the arial mount Quote
christianmg Posted August 28, 2011 Author Posted August 28, 2011 sounds like a loose peice of bodywork, thats what im hoping and not a leaf or spring, but how do you start looking for something that only starts to vibrate at 70?? is there anything that usually goes loose in that general area?? Quote
magic84 Posted August 28, 2011 Posted August 28, 2011 id give the bumper a little pull and see if it moves as air travelling at 70mph will have a bit of strength in it.... could also be wheel liners Quote
christianmg Posted August 28, 2011 Author Posted August 28, 2011 id give the bumper a little pull and see if it moves as air travelling at 70mph will have a bit of strength in it.... could also be wheel liners all feels tight?!! ... ?? Do you think it would be worth taking it to a garge with a ramp and shaking everything underneath to see if anything is moving there?? Quote
magic84 Posted August 28, 2011 Posted August 28, 2011 i'd say yes once your sure youve looked as much as you can, it may aslo be, the exhaust heat sheild or the brace under the car, but what ever it is as you say it needs momentum to happen so id be looking for something loose, im sure the more technical guys will have a few other ideas.

M13KYF Posted August 28, 2011 Posted August 28, 2011 probably need the rear discs cleaning. You may have a shadow on them or where the handbrake pad in the drum has left a bit of a deposit/rust from not moving in a month. Did you leave the handbrake on while you were away. Thats what I'd first look into Quote
christianmg Posted August 28, 2011 Author Posted August 28, 2011 yep like a noob I did!! was supposed to head down to the carpark and just leave it in gear, but ran out of time packing! can I do this myself or is it a garage job? Quote
M13KYF Posted August 29, 2011 Posted August 29, 2011 it depends how competent you are. Its not too difficult. It shouldnt take longer than a hour to have a look. You'll need to slacken off the handbrake before removing the drum. You find a access point on the disc/drum to turn the wheel. When putting it all back together you'll need to tweak back up the handbrake so it just very slightly rubs. Perhaps before you take it off spin the disc to get an idea of the friction, you may even feel where its binding after leaving it on for a month Quote
christianmg Posted August 30, 2011 Author Posted August 30, 2011 HMMMM!! not sure if this helps, but was felling around the back bumper and the small flap in between the two pipes is a bit loose, there is a bit of give in it like. so I was feeling underneath to see where or how I would attach it to make it more secure and I put my hand up around the back box (is that the right term) and there is a metal tray just balancing above the exhaust box?!?! Its just sitting there, I can move it any way I want?? Any ideas on where this belongs and could this be the boyo making the noise?? thanks for all the help! Quote
christianmg Posted August 30, 2011 Author Posted August 30, 2011 i think its a heat shield possibly sweet! ... I think? Is there any idea on how to re-attach it?? could it be causing the vibrations?? Its not too thin... similar to an oven tray? about maybe 2mm Quote
