Lift off clunk

[blambert]

Noticed the 182 has developed a nasty clunk/knocking noise.

Its intermittent though. To reproduce:

- 1st gear
- rev up to about 3500rpm
- take foot off throttle

As it jumps forward due to the cut in power there is a nice clunk noise from the front of the car.

Doesn't happen all the time. Engine mount?

What's the best way to check the mounts?

Exhaust hitting the subframe IIRC. Probably needs new engine mounts anyway. They're designed to fall apart.

Most likely down to engine movement. Could be worn mounts, or could just be something loose. Dogbone mount bushes are the most obvious culprit

Mine starts to do this asthe weather becomes colder. All mountings and bushes are new (ARBs, Dogbone stabilizer, Strut mounts and engine mounts). Only notice it in 1st and 2nd gear. Pain in the a*se, but there it is!

not unusual for a worn out downpipe gasket to cause a knock. Once the gasket is worn the springs loosen up

Tried rocking the engine to see if it clunks then.?

In all fairness, taking your foot off the accelerator in third gear at 3500rpm isn't exactly advised!?

Besides the point it still shouldn't be doing it!

I'd put my money on Dogbone bushes.

My 172 done the same

Noticed in a multistorey car park today that at full lock left there is a grinding/knocking noise from the front end.

Hmmmm? Related or is everything rubber perishing in this cold.

 

[Mister_Lee]

had the same on my 1.2- was down to dogbone gearbox mount working its way loose. Your grinding sound on full lock could be down to a worn cv joint

why is it not advised to take your foot off at 3.5k? mine does this when i pull off with lock on....im not scared lol
