Got the car up on jackstands today to ponder doing the diff bushing replacement and see not only what looks like my pinion seal has sprung a leak, but there's grease being flung off the inner, driver-side CV joint.

Pictures aren't the greatest, but can anybody confirm this/these? I'm off warranty, too ... has anyone done a pinion seal replacement themself?

Randy-My friend had a pinion leak not too long ago. He has not replaced the seal yet but we are going to do it soon. Look at my recent threads and ewill has placed the directions on the pinion seal replacement.

Ver-r-ry interesting! AND rather timely I might add. :highfive:

Ewill says there is a couple of special tools required (recommended?). Do you have a line on something tool-wise or are you still working on that part?

Uh, this seems too obvious to mention. But you do know the pinoin seal is a recall, right? I know its not all VINs, but I'm sure they'll replace it without charging you.


Or did I mis something....................

I do not have the special tool. I was thinking the special tool was a heavy tq wrench.. 200 and some odd ftlbs if I can remember correctly..

Tony-My friends car was not covered under the recall.

Really?!! I'd be pissed.
Randy, if I were you, I'd call me dealer anyway. See what they say. Doesn't matter what your VIN is, a problem is a problem.

Randy, did you get you seal replaced under that recall? If so I would think they would have to redo now as it must not have been done properly to have only lasted what a year? If you did not have it done under the recall i'd push alittle for them to do the recall now even if you vin should not be affected as it obvously is. What do you have to loose trying?

As I remember, my car was not covered under the recall. But, I think this is my third pinion seal ... I think. They replaced one since it was leaking and muffed it, so they did it again (I think) ... or they just fixed the second one so it wasn't leaking ... not sure which.

Anyway, maybe I'll give the dealer a jingle and ask them about it; that's a very good idea. If they want to see it or say they'll cover it, I'll pop the KARS kit off and boogie over there. That would be nice, actually ... I have no desire to start ripping into the diff and get in over my head when there's some special six-foot torque wrench or some such weirdness. As it is, I'm having Den_93's buddy do my diff bushing tomorrow 'cause I just don't feel like it. Geez, I'm lazy these days. :eek:

EDIT: Forgot to mention, there're no drip marks on the garage floor. Must leak only when in motion.

I have heard somewhere:cookoo: that they only leak when the diff fluid is warm... Who knows!!

Not unless you tore a boot! Which would really suck!

By the way, I changed my pinion seal because it was not covered under warranty or recall. I pulled the entire pinion out just to take a gander. Make sure there was no big chunks of anything in there and pulled the pinion nut with an impact, replaced seal, put back together with an impact. I never used a torque wrench and so far so good!

I have seen some CV boot leaks. I think I had one that the metal ring that holds the boot on was actually causing the leak.
I forget how it was serviced.
Seems like I could get parts for that. Check with Luke. It might need some special tools too.
That leak is pretty minor but it should be taken care of. That is a really small amount of grease.

I could tell you more about the pinion area leak if that picture was backed off and I could see the housing, yoke, and the pinion seal.

I have to have a serious talk with lollygagger about his avatars. :lol:

Am on my way to Den_93's buddy's house to have him change out my diff bushing ... he's got a lift :drool: ... and I'll take better pics when I'm there and post them up.

As far as lollygagger goes, well ... that's hopeless, IMO.

As for me, though I like 510's Megan, I still miss Dannystang's avatar. :D

I thought the propshaft was non-serviceable? <- at least that's what my stealership told me. :( Didn't I call you on that one? Pretty sure you told me the same thing ya swindler hahaha j/k man!

What's the matter with my avater? :lildevil: 2 >1 :lol: Aren't they hot enough?

Anybody have a CV joint sling grease before?
That looks like grease from the CV boot...too thick to be the diff fluid. I went thru the same exact thing on my 1st driveshaft. <- Might be time for a new driveshaft Randy if you don't have those crazy ewill tools :cool2: You couldn't even see the rip in the boot unless you grabbed it and torqued on it. Then it slowly flung out like yours looks like it's doing.

Try Cleveland Pick Apart....that's where I got mine for cheap.

Ewill was right on the money. Just got back from having my diff bushing installed. It turns out that the band clamp was installed (I assume at the factory) on a slight angle. I could actually wiggle it with my fingers. The guy who did the diff bushing (great guy, btw) straightened it up and was able to just barely tighten it with some visegrips. It's a bandaid until I can get a new clamp, and we'll put it on when I do the MMs and the FW.

This pic is not quite in focus, but you can just see that it's not quite straight (sorry, but photobucket is down, so this is straight from my camera at lower res):

I'm glad my buddy was able to take care of you. How long did it take?

Sometimes that metal ring that the boot mounts on isn't installed right, rare but possible.
If you are on that "leak" you should be fine. Yeah that clamp isn't installed right, I can tell from that photo.

LG, dude, you don't know the pain... :lol:
Long story... don't mind me, just do what you do and I'll have to deal with it.
;)

It took like 1-3/4 hrs but we also mended the CV joint clamp, plus he tack-welded the steel plates onto my KARS III kit. Actually, I think I'm going to have him do my MMs and FW installs, maybe a pinion seal and maybe the CV joint clamp and ... well, that's all I can think of at the moment. :D

Crappy pic ... wish I knew how to put those nifty little arrows guys draw sometimes to isolate what they're talking about. :banghead:

I truly do appreciate your input on this matter and you being here in general. You are part of what makes this forum the best!!! :thumbsup:

You have to get a graphics editing program.
It takes time and effort. I can see what you are talking about just fine.

Thanks for the kind words. People actually saying "thank you" is what keeps me coming back.
I love to help when I can.
