Ticking only when driving gets louder as i go faster

Just wondering if anyone has any ideas i've recently found a few faults while driving. Here is the small list :-

1. ticking when driving gets louder as I go faster but goes quiet when stood still even if revved in neutral. was thinking maybe exhaust are something on a drive shaft

2. theirs a clunk sometimes when going over bumps sounds like front end but unsure. was thinking a drop link etc

3. slight eratic idle nothing major just up and down between 800 and 1000


any help will be appreciated before I go to my local land rover specialist who charges a arm and a leg just to diagnose

What vehicle ?

sorry p38a

Stone in the tyre ?
2nd is probably bushes anti roll bar bushes would be a bet
3rd no idea

checked tyres cleaned all tread out still did it afterwards

Ticking could be exhaust manifold crack or blown gasket

particularly if it is like it under load, but stops on overrun - try "kangarooing" the throttle & see if the noise matches the throttle.

Cheers will give it A try tomorrow least it will hopefully be a reasonably easy fix at worst a new manifold
