Early LR3's had issues with steering knock. LR issued a new steering rack wich dampened the noises and clunk on the steering wheel. The front arb bushes also fail early, along with the front ball joints. LR issued a new front lower ball joint. If you have clunking in the front end, your issue could be 1 of the 3 listed above or all. My arb bushes and rack were replaced under warranty at 23,000 miles.
