i got me a civic, i've just had the brake discs and pads replaced, but mechanic noticed cv boot was cracked. that's fair enough! i choose not to replace been tight at the time. now i'm up for motorways this weekend and decide to get it replaced. i'm shopping around for prices, and noticing that this is a minefield.

my problem; sometimes the wheel makes a rattling sound when i turn a corner tightly.

this mechanic reckons its the cv joint "110 percent sure it is". didn't even look at the car but knew that. but a well known garage service did not pick this up when they replaced brakes last week, just the cv boot.

fair do's, i know mechs need the money, but i thought i'd be looking at about 35 pound, and as usual the cost has spiralled.

i'd like to know what the panel think, please

Your CV joints are a version of the old universal joint, but better. They
are bathed in grease and keep their grease from being slung off and are
shilede from dirt penetration by a flexible rubber boot that fits over the
joint. They are mounted to both ends of the driveshaft or as they are known
with this arrangment, a half-shaft. One end attaches to the tranny the
other end to the wheel hub. If a boot tears, dirt gets into the cv joint
and begins to chew it up. So if a torn boot is run too long there is no
reason to repace the boot, the joint must go as well. The cheapest way to
do that is with a rebuilt half-shaft (~$75?). So if you replaced a boot
and you are hearing a thunking noise when you make a sharp turn, you've
trashed the CV joint anyway. The CV joint will eventully break.
