is it the long one that goes behind the front axle between each wheel hub or the one from the steering box to the hub?
if its the track rod (the long one between both wheels) just give the end of the housing that holds the TRE into the hub a bloody good smack with a BFH (large impact device) on the casting this will release the TRE tapered shaft and it should just pop out, if its the the drag link, i used the same technique and it worked fine, some say to use two hammers and hit either side of the casting at the same time, i just used one really big one and it worked. all you need to do is release the pressure from the taper fit and it lifts out easily, are you replacing the TREs at the same time? you may aswell if you werent planning on it, do it, its pointless just doing the rod as you will need the tracking doing again after doing the TREs in the future.remember lots of coppaslip when you are putting it back together for future ease of removal.
