Blown diff AND clutch in GT
Hi folks, just thought I'd report my latest GT diesel misadventure. My '05 GT has done 60k miles, the last 20k with a performance module fitted taking the power up to approx 185 bhp with a noticeable increase in torque according to the seat of my pants and the alarming rate of wear on my front tyres.
I first noticed the clutch starting to slip during the winter and decided I'd nurse it until my bike was on the road for the summer so I wouldn't be without transport. It has gradually got worse but not much. Only really a problem when overtaking in the higher gears and I reckon I could have made it last until next summer if necessary.
Unfortunately, one of the gears in my diff decided to break up and punch a hole through the bellhousing. The warning signs I should've heeded were an increase in noise at higher speeds and a sound like a wheel bearing rumbling when cornering. Louis at Alfa Tecnico (a local independant specialist who I would recommend) warned me long ago that the diffs have a tendency to give up and suggested I have a Q2 fitted. I was intending to do that at the same time as I replaced the clutch but time ran out and with a few relatively quiet bangs from underneath while slow speed manouvering I was dismayed to find a large pool of gear oil on the floor.
I currently have the box out of the car and although a lot of bits of swarf have found their way into it there doesn't appear to be any damage except a hole in the bellhousing which I'm going to weld up. The box will need a thorough clean up and inspection but apart from that it will hopefully be ok.
Anyone who's contemplating a DIY clutch change should only make a start if they have small hands, an extensive tool kit with ball joint splitters, wobble extensions and some big pry bars. It's been a bloody nightmare and took the best part of a day to remove the box, the worst part was undoing the starter motor bolts (I've lost several layers of skin from my forearms as a result)
I'll let you know how I get on but I need to find the £1000 or so it's going to cost me for a Q2 diff, a clutch and a flywheel. I'd recommend leaving the clutch to the pros and I'd certainly recommend a Q2 diff if you have a chipped motor, if only to save you the trouble I'm having now. Good thing my bike is out of it's winter hibernation or I'd be screwed.
Despite all this I have every intention of keeping my GT as there's nothing else out there with the blend of performance, practicality and economy that is anywhere near as beautiful or has that Italian character that has led me to ride Ducatis for the last 10 years. I still love my car and I'm sure I'll love it even more when it isn't scrabbling for grip every time I put my foot down.
Big thanks to Louis for his patience and advice so far.
