knocking

Hi my name is Mike and i own a 2002 c220 cdi. I have had the car 2 weeks and i have noticed a knocking noise coming from the front suspension when i brake hard and also when i go over a pot holes can anyone help me. Regards Mike :wallbash:

I have noticed the occasional knock from the suspension of my CLK55. Not sure if it is the rear or front, but it is a usually a single knock, heard when turning going in reverse and sometimes going forward, difficult to say when but it may be when turning corners. I know that it fairly vague...

Hello, On my 2001 30K mile SL500: When starting from cold the engine runs at higher revs for 10 seconds then smooths out to 'normal' speed -OK. Engage DRIVE and move off and for the first 30 seconds to 1 minute I get a 'knocking' that (maybe) sounds like a dry pump trying to prime itself - maybe...

Hi all. hope everyone has recovered from christmas (financially I mean :D ) I have a knocking noise from the front suspension on my clk. I have replaced both lower ball joints and I am thinking it might be the upper suspension arms. I know it's a full arm. The question is do I need any...

Ive had my C250D for 2 years and its been great up until last month. Its a '98 non turbo, 5 cylinder diesel. I began to have trouble with air in the fuel. After the car sat overnight I had to crank the starter continuously to purge the air out of the system before it would start. I changed...

My 11 year old C200 has recently developed knocking noise when the brake is applied to slow down. It sounds like the ABS working but it is not because there is no knock at the foot pedal. It wasn't hard braking anyway. I have replaced the two front disc but it did not help at all. The brake...

Hi Everyone, I recently brought a Y reg smart car with only 57k miles... a year ago the previous owner took the car back for a factory recall for some shocks all round... I brought the car two days ago and when i go over small bumps it has a knocking noise from somewhere under the car... not...

Having seen all the useful advice on this forum I wonder if anyone can help me. I have an 04 E320 (petrol) with 72k miles, dealer serviced from new. It has recently developed a quiet knocking which is related to engine speed. This is only apparent at low revs when applying a little power -...

Seem to have developed a problem with the front drivers side wheel area when i go over any sort of pot hole or bump. The result is a knocking noise. Decided to check both areas tonight and whipped off the wheels and low and behold i can see a problem with one of the bushes on item 140 below...

Hello all , got a knocking noise on the o/s/f wheel area, changed top and bottom balljoints, anti roll bar bushes and links adjusted wheel bearings but to no avail, is there anything bolted inside the wing that could come loose and knock over bumps? it's driving me insane. 2001 s class w220 320CDI

Hi all, Having now identified a warped front brake disc (and thanks to Ian 124 Works having a solution) I am growing a touch concerned about the knocking noise under braking and when on bumpy ground. I did see mention of a banging noise on a previous threat but wanted to check with everyone...

I was just wondering if anyone has an idea what is wrong with the car? I have a w209 CLK and there is a knocking noise from the steering when going over bumps and if rocking the steering wheel, it is no great drama as the car is under warranty, just wondering if anyone knows what it will be...

A bit of an odd one this. I'm not even sure if it belongs under this category, so Administrators feel free to move it! I checked a load of the existing posts for something relevant in this category and wheels and tyres, but I couldn't find anything. Hopefully one of you clever chaps will be able...

My W124 CE suddenly developed a worrying "clonking" from the back end. It was quite hard to describe but it sounded like something either knocking the inside of the fuel tank/body panel or perhaps a loose suspension component. After putting up with it for a couple of days - and being unable...

I can hear a knocking noise coming from the front right of the car when going over speed bumps. I took the front right wheel off and could not see any loose bolts or worn bushes and the suspension looked ok. Obviously bushes are under much greater strain when under load and a simple inspection...

hi there all!!! what a nice day it was today! i had the day off so decided it was time to eliminate that stupid knocking sound from the suspenstion, after looking up some threads on the forum i decided to look closer at all the components, and guess what, to my surprize i needed to replace the...

Have discovered that an annoying knock from the rear has been caused by a failed subframe to floor connector. I have found a repair kit but it fails to state if it each or for a pair. Can anyone help? The part no is A2103505808. Thanks Andrew

Hi Guys, My car has started making a knocking noise from the front and somtimes feels like the rear end the sound kind of travels so you cant tell where its coming from but feels more to be more from front end (so annoying). Its when i am driving along hitting potholes or uneven surfaces when...

I have recently purchased a 1994 SL 500 and it has developed a knocking noise from what sounds like the steering or suspension. On a flat, smooth even surface, there is no noise but when you go over bumps or cobbles there is an intermittent knocking/scraping that sounds quite bad. Could it be...

Now I haven't done this, but am I correct in thinking that if I accidently took my automatic out of gear on a motorway, the only way to get it back into Drive (D) would be to stop the car... on a motorway??? ie once the car is out of D you can only put it back in while stationary. Is this...
