mrkieran23 Posted June 6, 2015 Posted June 6, 2015 So i own a 54 350, done 43k. Recently i notice that some times i get a grinding noise coming from front of the car at low revs with mild acceleration. Its hard to explain but i hear the nice engine nice engine growl but i also hear and feel a grinding noise, happens with mild acceleration 1st, 2nd n 3rd, not tried other gears, its hard to explain and i doubt my phone would pick up the noise, it still has warrenty so will call dealer about it but would like to be armed with some info. i know typically they say the trans on these are noisy but this doesnt feel like its normal as its only just started, last couple week. I prob only drive the car 30ish miles a week. all thoughts and comments welcome.
coldel Posted June 6, 2015 Posted June 6, 2015 Could be rust on the discs, if you leave the car a few days it builds up and will make a grind noise which lessens as you drive the car?
mrkieran23 Posted June 6, 2015 Author Posted June 6, 2015 I considered this but ruled it out due to only doing it with mild acceleration, if it were this i would think it would be more pronounced the slower i went ---- would love this to be what it is though
a2orry Posted June 7, 2015 Posted June 7, 2015 Could be rust on the discs, if you leave the car a few days it builds up and will make a grind noise which lessens as you drive the car? I would have a look at the inside faces of all the discs . Only doing 30 miles or so a week the pads could be jamming up in the caliper .outside faces of the brake disc s always look much better than the inside.
Dicky Posted June 7, 2015 Posted June 7, 2015 Can you feel any vibration through the steering wheel or elsewhere. I'm no expert but I would be thinking about either wheel bearings, altiantor bearings, front pulley belt bearings etc. I would have thought they may well grumble more when under acceleration load?
mrkieran23 Posted June 7, 2015 Author Posted June 7, 2015 I feel it through my feet, the pedals. Will get it up on Ramps n have a good look... Not drovd many zeds so have nothing to compare it too
chrisday1990 Posted June 8, 2015 Posted June 8, 2015 Check the heat shield behind the disk is not rubbing, I had this 1
Rock_Steady Posted June 8, 2015 Posted June 8, 2015 Check the dust shield behind the disc, it may be warped, best thing to do is put the NS window down and go round a round about, you'll definitely hear it then.
mrkieran23 Posted June 10, 2015 Author Posted June 10, 2015 Found the noise, started a new thread. appears to be coming from the propshaft
