Drain plug
Reply #33 –
Exactly thunder. Next time i am going to use a pipe reducer lets say 1/2 / 1/8 and drill and tap the small hole for a GM O RING plug. Seems like we are on the same page. You are correct that the pipe plug needs some sealer. The guys are bugging me about that aspect of the repair. Also here is another place i use them. The GM 10.5" floating axle final drives burn out outer axle bearings. They have a nasty habit of blocking the fluid from getting to the outer bearing set. SOOOOOOOOOOOOO!!! I drill a hole in the cover and move the fill mark UP app 1" This allows the oil to seep out to the bearings. You can also use this for a drain plug or d fill plug repair on a final drive that has a stripped fill plug on a final drive axle. Some guys do not clean out the fill plug in the side of the rear and strip the square end of the plug and cant get it out. Just another scenario. Thanks
Example!
