I replaced both front anti roll bar drop links max 18 months ago and they are starting to knock a bit already. At least they are cheap to buy and easy to replace
I dont think our unsurfaced back road as access to the house helps!
I replaced both drop links yesterday, on both the lower ball joints were worn out - tops didn't seem to bad. I guess thats it fine for another 18 months Although my 1998 Freelander is showing very early symptoms as well!
Have a Discovery but had same problem -I went thru quite a lot of these, think I changed both sides 3 or 4 times in something like 3 years after buying cheapos and then bought genuine ones. No probs since and they've been fitted for over 2 years.
