What size/type wrench do I need for the transferecase plugs and d30 plugs? I think I have the 242 t-case.

 

D30 uses a 3/8" plug that you can just use a ratchet extension to remove. Same with the rear unless it's a d35 then it just has a rubber plug you pull out. NP242 uses 10mm plugs if I remember correctly??

 

231 big adjustabe wrench some 35s also have 3/8

 

t- case 24mm wrench

 

This was spot on. Made my shopping experience short.

My diff fluid smelt horrible. Don't know if that's normal. There were no metal shavings. All the gears looked mint. My front diff fluid however was so old, it was like black sludge.
