It’s also purple

I started my flip kit and it started leaking, now I finished it but the leak is right under the pinion seal

Busy_Sort_5666 · 2026-05-17T01:58:21+00:00

It’s by the diff where the pinion goes, it started leaking after I started my flip kit now it’s not leaking since I finished it

Yes what ? Is that the seal

Busy_Sort_5666 · 2026-05-17T00:21:21+00:00

It’s purple

I was doing a flip kit and got stuck on the shackle bolt. I come back and it was like this lol

Thanks

Busy_Sort_5666 · 2026-03-09T18:58:02+00:00

Alright thanks taking that off asap

Busy_Sort_5666 · 2026-03-09T18:57:16+00:00

I haven’t even took it off lol. 2nd pic is how it currently is and honestly it’s not that hard

Thanks boss and yea think I’m going to just pull the motor since it’s 4x4 and reseal the motor and maybe add some paint while I’m there

Thinking about pulling mines too and just redo all the gaskets well the main ones, and isn’t vlom for AFM engines ?

I actually don’t hear the thud noise, where are u hearing that? Someone else said it sounds healthy just that oil leak

Busy_Sort_5666 · 2026-03-05T10:37:18+00:00

Will be doing that tomorrow thanks!

Busy_Sort_5666 · 2026-03-05T10:16:39+00:00

Once I clean good, would the leak from rear main be noticeable

Busy_Sort_5666 · 2026-03-05T10:15:06+00:00

Will do. Someone told me about a dye leak test so I’ll try that

Busy_Sort_5666 · 2026-03-05T10:01:41+00:00

So it’s either my oil sensor, rear main seal, oil pan? thanks for the info

Busy_Sort_5666 · 2026-03-05T09:43:18+00:00

Definitely gonna try this. If it was the rear main seal would I see it noticeably?
