hello im bobby i have a 98 jimmy with the 4.3 im in need of the size of the rear end plug my plug hole is striped and the owner befor me just stuck a bolt in ther and i cant seem to find anything on the plug bobby

Are you talking about the drain plug on the rear axle differential cover(pumpking cover)?

most of the time its cheaper and alot easier to get an aftermarket diff cover or junk yard with the plug in it

yes sorry im talking about the plug on the axle

The 98 Blazer comes standard with a fill plug, not a drain plug. Dorman does make a aftermarket cover with a drain plug. If you have the factory cover on your Blazer, you are talking about the fill plug. I don't know the size, but you should be able to pick up a replacement at most salvage yards. The fill plug is not located on the cover.

You say the hole is stripped, so you may be asking so you can tap new threads. I don't know the size.

yes its a fill plug on the axel the cover dose not have a fill plug and i cant get one with a fill plug in it because i have the 7.5 rear end

The plug is pipe thread.

Bobby, I'm not sure of the plug size, but you can tap it next size bigger and bring it back to standard with a helicoil or install the next size bigger plug

I also believe it'* pipe thread - hardware store stuff

luck,greg

I'm sorry, I assumed, you know to remove the back cover and clean out thoroughly after you tap - (metal shavings)

luck,greg

yes guys i got that problem all fixed up now for the help
