85lebaront2 Posted August 18, 2023 Share Posted August 18, 2023 Why? I thought about adding one to my D60, but when fluid changes are done so rarely it's not like it matters much. Pulling the cover also gives you a chance to inspect everything every few years. It's been talked around here, but the Ford 9" doesn't have a cover. Instead you pull both axle shafts and the driveshaft and then remove the third member. And with my 9" that's been rotated up to compensate for the suspension lift on a short wheelbase early Bronco, there's a substantial amount of gear lube that won't run out, so you end up having to sop it out with a rag or something. I don't have a drain plug on mine, but I wouldn't describe it as a mistake in my case. I hit the diff on enough rocks as it is. I don't want to do anything that would cost me any ground clearance there. Here's what I did on my friend's 1995 F350 10.25" Sterling. Center section is a casting so is pretty thick. I just drilled and tapped for a 3/8 NPT plug and used a hex socket plug that is screwed in almost flush. Link to comment Share on other sites More sharing options...
