Clunk noise after clutch and flywheel change
Discussion
Hello I got my clutch changed an flywheel on a corolla d4d and when you lift clutch in first or second a bit quick it sort of clunks it doesn't do this if you lift slowly. I also get the same noise if I floor it in first as it moves it clunks quickly as it jolts forwards. It is a solid mass flywheel now instead of dual car drives lovely if anything better than it ever has but the noise has me worried. I don't mind if it's the normal for a solid flywheel to make that noise a bit longs it's nothing bad.
Backlash in the driveline can lead to a clunk when you take up drive and also on torque reversal. Do you notice more drive line shunt now?
Could also indicate that the engine/exhaust are touching something which could be because it's moving too far (mounts failed / unsecured) or just positioned too close.

The car does want to take off quickly now when lifting clutch but I don't have any vibrations etc or anything too weird just a clunk noise. This happens if I rapidly lift foot off accelerator in 1st or push it down quick in first as well as when lifting clutch up a bit quick. I can minimise it by driving lifting clutch slowly etc and not taking off full pelt in 1st.
You may find this is just drive train shunt one of the many reason DMF are used in the 1st place you have removed this dampening , but now you have removed this component 
may be worth speaking to other owners or driving the same model where this work as been carried out previously , I am no lover of DMF's but in correct use they dont give any bother and are there to serve a function inc transmission gear chatter , on a diesel long term your transmission components wont thank you for its removal , basically what I am saying is you have stepped a bit into the unknown

Dual mass flywheels, if i'm correct split up the torque going though the drivetrain into two stages, to make the torque going through smoother,or less stressful on the clutch?
Single mass flywheel just might be struggling a bit, some cars you can get away with changing flywheels to singles, some you can't!

It was quite an expensive set about 480 for flywheel and clutch car drives better than it ever has just weird noise I can reduce the noise or make it disappear when I don’t drive like a knob haha. Hopefully it’s just the single mass flywheel being less dampening. It’s a 12 year old car didn’t see the point in spending stupid money on a dmf for it and then having to replace the dmf again when it fails. The old dmf and clutch were absolutely cream crackered
It may be worth checking all of the nuts and bolts that were loosened during the clutch change, perhaps something wasn't torqued up properly during re-assembly thus allowing movement somewhere in the drivetrain. If possible, I would want to do this with the weight of the car on the wheels too.

I think one of my engine mounts is naffed has bonnet up and got someone to pull towards and backwards on the clutch lifting and the engine rocks a bit much and looks like it's knocking on stuff. I could be wrong.
You could also be right 
and the change to the solid FW may have brought this failure to light, apart from the fact its been disturbed anyway which seldom helps an already failing component 
t roads no horrible noises so that's sorted.Gassing Station | Engines & Drivetrain | Top of Page | What's New | My Stuff
