Hi all.
Did a bit of reading but most of the stuff I found was pointing to worn out diff mounts...
At this point I think I'm only getting more confused. Need some help.
The car:
LC 105 1999
215000 Km
Petrol/LPG - Manual
Bought a few months ago. Had the clunk already.
The problem:
I would describe it as a thud, or a clunk coming somewhere from the driveline... You can feel it more then hear it.
It seem to happen every time the car switches from accelerating to decelerating and vice versa.
The easiest way to make it happen is drive slow through a flat terrain, step on and off the accelerator while the car keeps moving.
For those who ride motorcycles, it feels similar to when the chain has too much slack and needs adjustment.
When driving normally, this feels particularly bad when starting the car and going uphill for example.
- Accelerating on 1st gear
- clutch (small clunk!)
- Put on 2nd gear
- release clutch (big clunk!)
Another clue:
It also happens with any other gear. Releasing the clutch REALLY SLOW can avoid the clunk sometimes...
I'm no mechanic whatsoever, but I like troubleshooting things.
And for this one, I wanted to be sure I have a clue of what is going on before taking the car to someone to have a look (I do not have a mechanic I trust...)
Following the lead on the similarity with the lose motorcycle chain, I started looking for signs of free-play in the various points in the drive line.
It seems to me that the free-play I've found on the front output shaft is a bit excessive. My reference is that the rear output shaft does not have any.
I've read a bit about how diffs work and the backlash adjustment... Feels like that could be my problem. Is there anything else I could test before taking it to someone?
I've recorded a video where I've checked the free-play when lifting up each wheel independently. To me, it kinda also points to the front diff (or something between the front diff and the wheels?)
If the front diff turns to be the main suspect, should I take it to any general mechanic or do I need a diff specialist of sorts?
Any idea of how much $$ I am about to spend (Syd Australia)?
Appreciate any comments and advice on where to go from here.
Thanks,
Ed.
