After much soaking of seized bit in diesel, penetrating oil etc and getting no where i was ready to live without it. Until some kind soul nicked the radio aerial off my works van. Off i went to the scrap yard to see if i could find another one (Halfrauds wanted =A313!). None to be had at all, but hello whats that familier looking shape sat over the back....a Range Rover....oohh.....an auto one even better. Diff lock lever works ok on this one. Took it off and took a chance it would fit my Disco. Cost me the grand total of =A35. A quick clean up and regrease and it was off with the old seized one. New one bolts straight on and hey presto it works, well the diff lock light comes on and the lever moves well over to the left. How can i check that it is really engaging the diff lock?.
