Jolt when coming to a halt

It has taken me a few days to figure out how best to describe this one!!
When I apply the brakes, gently or hard, and the truck comes to a stop, as it has stopped, it is like there is a bowling ball somewhere under the car. I don't mean I hear it rolling around, but the car feels like the bowling ball has rolled forward and hit something, making the truck feel like it hadn't stopped properly, when it has. Initially though of engine mounting, but they all seem fine. Any ideas?

Thanks again.

check for longitudinal play in propshafts, gearbox, transfer case .... just make sure first that u dont have a bowling ball or other rolling object in the boot

Auto or manual, had similar issue with my auto, turned out low oil in auto box, was like gearbox was still pushing even tho car was still felt like a thud at first, might be similar.

Good luck mate

Try backing the handbrake off a bit - it could be catching and at high speed you don't notice it, but at low speed you do. My 300Tdi was a bugger for this - I struggled to get a balance between the brake grabbing and having a resonable lever travel.

Cheers!

Thanks guys for the responses. It is an autobox. It goes in for a service in a couple of weeks so will get them to check it out. ****es me off though when they test it and they say its nothing to worry about, its a Land Rover!!! I will update you if I get is resolved.

Cheers
