Clunky Puma Gearbox

As others have said it definitely improves once you get a few thousand on the clock, it is also a lot more fluid once warmed up. When I took one for a test drive it was very embarrassing - I stalled it once - however now that I have it I have adjusted my driving accordingly and almost never hear any cluncks.

I would like to thank all members that helped out with my concerns, we will be proceding with our purchase of the 90 :D

I had major clunking on my Puma since brand new.

After much fighting, LR replaced the gearbox - no improvement.

After much more fighting, LR replaced the clutch - no more clunking.

07 Puma with 90,000k's on it since new. Had driving clunks at various times throughout it's life. All comes down to clutch handling skill, as even with the faults below you can drive it clunk free if you are very carefully. But there have been several mechanical causes too:

1 - pinion spines on rear diff were sloppy, they loctited it and that's been quiet since.
2 - Axle splines in hubs wear out every 60,000 ks or so. causing clunking on take off.
3 - Clutches, if a spring breaks it will clunk. I've had 3 clutches, most recently just after the warranty expired - luckily they covered that under warranty. The clutches seem to last a few months and then go back to their clunkiness. Living with it now.

Clunking is actually the least noise to worry about on a defender, Particularly the Puma. Be more worried about chirping when you switch off, or strange vibrations...

dunno but will have a look. It had a new transfer case whacked in it last week so I'd hope the LR specialist they are would have noticed.

thanks

edit
Just looked, it appears to have black rubbery sealent in it. I'm looking at a half moon drain hole 4" in front of the transfer. Should that be in there, or should I hook it out?

I have just re-read these posts and yes the chirping.
Thats why we call him "Uncle Buck" If you have seen the movie you would understand why!
