Vibration noise around 1200rpm
Slight vibration sounds like coming from front somewhere. When around 1300rpm decelerating or acclerating in gear in 1st or second mainly.
Only seem to happen since putting 35s on.
Is it drive shaft load or engine mounts?
Anything else I need to look for.
If normal because of extra unsprung weight then Im okay with that too
Any other speed and rpm is fine.

Would a worn universal joint do this? Or would a worn one do it constantly?

I'm wondering if its the usual TD groan on low rev's which is like a harmonic vibration that goes through the drive train and yours is now happening because of the bigger tyres perhaps?

Hey AB
Thanks
I have that low rpm 1st and second gear gearbox chatter rattle (gear rollover) before the tyre changeover. I was aware of that being a TD42T thing. (this I can live with as its a TD42t thing lol)
This new one is different. Doesnt last long at all. Definately the vibration rpm because the heatshield that is on the passenger engine mount rattles too.
Im not good at articulating but its not a heavy vibration.
Not light enough to be a rattle

i had a shake in the drive line. changed the clutch gone. turns out the dampening springs were cactus in the clutch plate. i mostly noticed this at low revs low gears.
i wouldn't just assume it was this.
if its worth doin its worth over doin

you could be onto something.
Im not slipping but I do think this clutch is on the tail end of its life.

This is fairly normal with a TD42 ... it is usually a harmonic resonance noise - gearbox chatter, and you will only get it at low revs

Thanks HappyGu
I have the gearbox chatter already before the 35 inch. Its like a rattle in 1st and 2nd at low rpm. That I can deal with.
This one is like a vibration like a fast brrrrrrrrrrrrr sound. Doesnt last that long as soon as the rpm increases.
You could be right. Maybe gearbox chatter comes in extra sounds.
To me its like low RPM is where the engine is shaky and it is shaking something?
I could be wrong.
Besides that. Every other rpm and gear car is perfectly fine.
Im sure the extra unsprung weight of the 35s has changed something somewhere lol

Also do we need this heat shield circled It only has one bolt holding it and no matter how I bend it . It still rattles on that low rpm
Seems like its there to keep heat away from the passenger engine mount
