Knocking when engaging clutch

[Roy]

I hope this little tale helps some other Skyline owners out there.

About 10 months ago i purchased a lightened flywheel and 5 puck clutch from a performance shop in Sydney. (Not my usual mechanic)

So the very first time i drove it with new clutch, there was a knocking noise/vibration when engaging the clutch. I gave it 1000kms to settle as instructed then returned to complain about the grabby style of the clutch and also the knocking noise.

I was told that is what puck style clutches are like, and the knocking is my diff and U-joints, which need replacing. They would book me in the next day and repair for about $1000

So months have passed with me waiting for the thing to go BANG, including about 10 track days. Now the vibration got slightly worse (minimal) but i also mastered the art of driving around the problem.

Anyway with some much needed HP coming my way the next few months i decided to bite the bullet and get it all fixed. Now i do much of my own servicing:rolleyes: so the car only sees my mechanic for major services (once in 10 months)

My usual mechanic rings me and tell me today car is fixed, broken gearbox mount, $280 including labour (part was $170 alone)

Now when i drive the car any knocking is about 95% eliminated. Read PEFRECT considering 10 year old car with 135,000kms.

So this gets me thinking the gearbox mount must have already sheared one of its mounts when i had the clutch installed.(As the problem became evident that day) If i had of taken the car back to where i had the clutch done were they planning on charging me approx $1000 for a gearbox mount, only send me on my merry way? Plus driving around withthe broken mount has probably done some damage to bearings in the box???

Goes to show some mechanics must get away with charging some serious coin for fixing simple problems.

So to those mechanics and shops who rape for the quick $$$...:shake: ... you wont be seeing any more $$$ from me. My usual mechanic isnt cheap but can never really complain about the servicing.
