After the nightmare I had getting the rear nearside drive member nuts off I thought I better do some preventative maintenance and remove and coppaslip the fronts too. The offside front ones came off no problem and were greased, replaced and torqued up (65). The nearside ones weren't quite as easy and I only managed to remove two of them. Even after blasting them with WD40 and giving them some heat they wouldn't budge and when I put my large breaker bar on them I managed to shear 2 of them off so far - not good!
Looks like I'll be stripping down and rebuilding the front hubs etc now too, arghhh!!!
A blog about my 1989 Land Rover 90 (Defender). It's here so I don't forget all the stuff I've done to it and will also hopefully be a help to anyone else with similar issues!
