Ive noticed over the last few days a thud when I'm braking from what feels/sounds like the middle of the car underneath. I thought at first it was something in the boot or wheel well but it's got worse very quickly.
It's does it if I brake fairly sharply at any speed.
I've also noticed some knocking from the suspension. Could it be related? Different type of noise for sure.
The knocking sounds like anti role bar or ball joint but the thud when breaking is a loud dull thud.
Any help and as always I will be most grateful

Loose brake pad ?
 
Id be surprised if it were as it doesn't sound like its from either side. More in the centre. And also more of a thud than I'd expect from a brake pad. It's as if I've got a tool box or something heavy in the boot that's moving
 
Maybe. I have suspected a centre bearing with excess play. I guess I'll have to get under it and see if anything has obvious movement that it shouldn't
 
So I found the issue, anyone know if this will need a bush or full wishbone? Easy job?

First thing I'd do, if you're doing it yourself, is buy bith bushes and new bolts etc .. then work out how they go together, cut the nackered ones out, it looks pretty easy .. ;) That's from someone who's never done a RangeRover bush though I've done loads of Landrover Disco and 90 and Defender bushes .. :)

I'd guess that once the bolt is cut the sides will slightly spring out so the bushed might be pushed in relatively easier than needing to be pressed in. Use some washing up liquid as lube for the rubber .. :)
 
Got a price for the complete wishbone from local factors and its onto £40 a side. Easier than the hassle of pressing in a bush so I'll do that
 
I'm glad you asked lol. About 2 hours ago I realised the answer to that is no.
So it'll just be replacing the bushes tomorrow. And I've found a guide on here about that which is super helpful as always
 
just changed all mine last couple of weeks. it wasnt a quick job. i started to cut the bolts and found the steel very hard so the blades blunted quick so i when and bought some dewalt blades for my reciprocating saw. cut the bolts at both sides for the rear top bushes and suport the hub cause when you go through the bolt on the last side the hub will drop down and will strain the flex pipe to the brakes.
 
Your not wrong about it not being a quick job.
Took me about 3 hours to do the drivers side today. Ran out of time to do the other side. The old bush had been welded to the hub. Not a pretty job either. Had to grind off the welds and then use the socket and bolt method. Snapped 2 bolts and stripped the thread on another. Got there in the end though

Think I got off lightly then cus the bolt took seconds to get out. Cant understand why someone had welded the bush in though. If it was lose then it was a quick cheap fix.
Hoping the passenger side isn't the same but that's Saturday's problem
 
Don't forget the bolts are cam adjusters also on some of them so put them back in the same position and then get tracking checked. My inner rear track rod bolts had seized in the bushes which was the hardest part of the job.
I purchased a bush press kit which was great as without that or the right size sockets they are stuck in.
Also make sure the handbrake is off or the bolts might not go back in.
I have a nice 2 ft breaker bar also.
