hi i bought a 300tdi, and ive taken it offroading as you do but without relising about the wading plugs !!! im missing both and been wading, ive never heard of these before as new to the land rover seen and just asumed you went off roading how wrong was i, it seems that the muddy waters got in to my bell housing and clutch and now when i use the clutch it grinds, only when moving in car tho not at stand still, but only when clutch pedal is down not up,but gears are fine go's in every gear perfect no noises gearbox seems fine, so ive been told this should be the release bearing which i can understand as a wet muddy bearing is a no no with any bearing , but alot of mates who have had discos have never had them or mentioned them and had no problems, but clearly i have, and it started 30 mins after wading so clearly was what caused it , so thinking water musta dryed out then started making noise, is it a hard job replacing being the weight of the gearbox/transfer box is huge lol, has anybody had this problem before just for advice, only had disco a week ahhhggghhhh, and a 5 pound set of wading plugs are gona cost hundreds now help please !!!!!
