Question

Car makes knocking noise when turning left, but only if accelerating at same time?

Answer 1

Could be your anti rollbar droplink knocking or bottom ball joint or some other part of your suspension, I'd take it to one of the big chain (ATS Quick fit) garages and get them to do a free health check, It might just be a worn bush. I find ATS very reasonable and honest but I'm sure other people have had problems so it just depends on the specific garage, try a few garages or just tell them you're taking it to another garage for a second quote after the've told you whats wrong with it. way they'll be more likely to be honest and competitive about the price. Hope this helps

Answer 2

I used to have a Peugeot 106 (Shared chassis with Citroen Saxo)



On my 106, as I cornered left while accelerating I would hear a knocking noise, but it was beneath me in the transmission tunnel! I was worried similar to you, I had everything checked, loosened and re-tightened. It still was there. In the end, I discovered what it was when my partner was driving and I was tailing tailing her, I saw the exaust moving excessively bouncing of an exhaust mount. The screw had rusted away, but it hovered there as though attatched, until it was forced right by turning left while accelerating, then the mount dropped slightly, and knocked the exhaust!



Nothing serious in the end, get your car up on a ramp and start vigourously moving the exhaust side to side from front to back, see if it is loose.



Good luck.

Answer 3

Sorry , only Mercedes-Benz

Answer 4

its more than likely ur cv joint or bearings in your steering

Answer 5

check the anti roll linkage...... Had the same problem myself, they are really cheap and easy to sort yourself!! think ours was about £10 from local motor factors and the only other thing you need is a spanner the right size..... was about a 20min job.... you may want to spray the bolts the night before with wd40 or plusgas just to loosen the gunk and road muck off a bit!!

Answer 6

Hi, I did have the same problem, First i thought that 's my cardan.

But wasn't that. it are the brake pads that knocking in their housing.

remove the brake pads and clean it all up, then a Little grease on the sliding parts NOT ON DISC OR BRAKE PAD.

It should ride and brake silent now.

good luck.

Answer 7

Check all the engine/gearbox mounts are good condition,(or even fitted) the motor could be 'floating' and putting extra side pressure/torque on drive shaft

Answer 8

If the drive was replaced, was it new or secondhand. The cv might not be great or there is also a bearing attaching the shaft to the engine for support, this could also be faulty. Return to where it was fixed and get a report.

Otherwise there is also a bearing on the top of the shock absorber but very unlikely to knock

Answer 9

Did they replace the bearings? That sounds like a bearing.

Answer 10

I don't know the citroen, but most cars have a CV joint AND an inner UJ to look out for.

CV's go very quickly when the gaiter is not right as they get muck inside and wear like crazy, so watch for a bad install.

If it's mainly left turns was it the left hand CV you had done? Tends to be the CV on the same side as the turn - the inside wheel turns more on a corner.
