The reverse light stopped working a couple of days ago which made it "interesting" reversing down our dark lane to the garage at night. It would come on as you put it into reverse and then go out virtually straight away. I looked up how it works and there is just a switch that screws into the top rear of the gearbox. This is dead easy to get to by removing the middle seat cushion section and unscrewing the cover beneath that. It just required another full turn clockwise into the gearbox housing and now works perfectly again :) While I had the cover off I used the opportunity to give the handbrake mechanism a good clean and grease too.
I noticed that the rubber from the offside rear bump stop was missing so thought I better replace it. I got the new part (basically a big chunk of rubber moulded to a metal bracket) and hoped it would just be a case of unbolting the old one (just the rubber was missing)... I managed to get both bolts half undone but as they are well rusted on and with a socket on the bottom and open ring spanner on top (can't get anything else on) I can't get enough pressure to remove them anymore :( Looks like a job for the angle grinder when I have time to attempt it again!
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!
