Knocking noise when changing gears.

[bash247]

Hey Chaps,

My 182 has recently developed a knocking noise when changing gears from first and second or when I take my foot off the accelerator. When you sit in the drivers seat, you can hear / feel the knock is coming from the left hand side of the car. The gear changes aren't as smooth as they used to be as well as the car juddering or "kangarooing" when moving in traffic or downshifting.

I guessed it was one of the mounts so decided to check out the dogbone mount and top engine mount. Both seemed solid and didn't budge. Before, I remove the battery and check the upper gearbox mount, would there be any other suspect?

Additionally, could someone let me know how to replace the upper gearbox mount if it is that.

Thanks

Need to change the lower gearbox (dog bone) mount I think.

I have the same knocking noise and just replaced all mount, apart from the dogbone because it didn't arrive in time. The noise is still there albeit fat less. The upper gearbox mount is quite easy to do.

Remove battery and you will see it. Undo the 3 bolts, but the 2 outer bolts have a nut on the underside which can fall out and it's difficult to get them back in, so I would suggest you get someone to hold them in place whilst you swap over the mount and then put the bolts back in. Then put the battery back in. You can take the airbox put for better access like I did.

Also make sure you support the engine and gearbox from underneath.

@bash247 that's the dogbone mount. Could be the upper engine mount but I'm confident it's dogbone.

You want an evol one or some purple powerflex bushes in your old one.

Thanks guys. I've ordered a replacement dogbone mount that should arrive today or tomorrow. I plan to replace that first to see if it sorts it out.

Im looking to powerflex my old one when I get the chance to do so. I'll let you guys know how I get on.

Firstly, loosen the 4x 16mm bolts on the upper engine mount, and pull the engine towards you. Nip the bolts up again.

You didn't need to buy another dogbone mate just the bushes that knacker. Should've just got the powerflex bushes

I know mate but money is a bit tight at the moment so the dogbone was a cheaper option. Only cost £15 from a friend. Will keep me going until i can powerflex the old one

So just a quick heads up. I removed the dogbone mount that was on the car and it appears to have a powerflex bush already installed. I replaced it any way just to be sure it wasn't the dogbone mount but the knocking noise is still there.

There is a slight gap in the bush but I don't see that would be the problem. I've attached some images.

Have you tried what @Budgie said?

 

[bash247]

Just saw that. Need to wait for the engine to cool down a bit first.

Man up, Jessie.

(Stick a lump of rag on the inlet and you'll be able to move it no problems..)

Can't loosen up the bloody bolts Haha. Currently trying to source a bar / breaker bar or something.

 

[bash247]

Those bolts just don't budge. I'm gonna leave it to mechanic to sort it out now haha

 

[arranshuker]

Spray them with Wd40 or similar for the next few days.

They're on very tight btw lol

 

[bash247]

I've soaked the bolts in a ton of wd40. Will give it another try tomorrow.

Have you got a big ratchet with a deep socket or like a breaker bar or somethjng? Or an old torque wrench for leverage?

 

[bash247]

Unfortunately I don't have one. I'm gonna try and source one or worst case just buy one.

So an amusing update for you guys. Got to the bottom of what the knocking noise was and it wasn't the mounts or the bolts being loose. It was the bloody fatty induction kit tapping the body
