well tried to lube the LC over the weekend...did lube the front and rear driveshafts and found all 6 zerk fittings...that was a piece of cake. On to the birfields fill plug. Tried every tool i had (6 pt, 12 pt socket, crescent wrench, open ended wrench) and couldn't get the square plug/bolt to loosen...started to strip and stopped. Customer at Sears overhead by conversation and said to try and find a 16 mm 8pt socket.. of course which Sears don't carry anymore.... What else could i use until i find the 16 mm 8 pt socket?? Vise Grips..
