8.8 4L10 Rabbit hole

Started my swap in tonight. As with any project one thing leads to another and...

I started by taking off the brakes out and noticed a bit of end play in the axle shafts so I opened up the diff to have a look see. There wasn't much fluid. The scene was very black. The odd part was if you rubbed your finger on the gears the oil was relatively clean. Spider gears had a little pitting but no cracks. Ring gear looked and felt food. It felt like a ~tight diff from the git go. My best guess is the clutch packs are worn and will affect the end play but this is some thing I can't seem to find a definitive answer on. I measured the end play at .080" and .085". How much end play should you have on an 8.8?

Not an answer, but a comment. From what I've read those LSD parts are really aggravating to get back into the carrier. Since it's already open, you might want to just install a locker. Might be easier in the long run.

Also, if you don't get any good help here, you might try one of the Explorer, Ranger or Mustang forums (since they all use 8.8s).

Mine looked the same as you describe, everything was black. The clutch packs were worn so bad there was no resistance. I believe there should be something like 35-45 ftlbs. The spiders were seriously pitted and galled. After looking into the cost of new spiders and clutch packs it was cheaper to buy this.

It's hard to beat $219 shipped for a new carbon fiber Ford Racing LSD.

exactly what are you measuring? The amount the shaft pulls out of the end of housing or ring gear to pinion movement?
The axle will move a lot in and out. Normal. The factory clutches last about 25k give or take in the 8.8LS. There are better ones and better combos of installing them. Easy toa find on the net.

Here's a great page showing how to replace the LSD Clutch packs - it actually doesn't look too bad.

He mentions end play, and the spec for it, at the end of the article.

Don't forget the gear setup cost/hassle that comes with a new carrier...

A lunchbox locker could replace the spider gears without gear setup: http://www.jegs.com/i/Powertrax/754/92-0688-3127/10002/-1?parentProductId=

The same site that has the Ford Racing LSD will sell you a new Ford Racing R&P for $139 and an install kit for $79. Add that to the cost of the LSD and the total is $437 vs. the lunch box locker for $521.

Granted it's not a locker, but depending on what your intended use may be, you get all new axle internals for pretty cheap.

I agree - I'm not in love with that locker, but it would not require any gear setups. Gear setups can be expensive, unless you can do them yourself. That's also the only lunchbox locker (as far as I know) that will drop into an LSD carrier.

And there are many advantages of lockers over LSD, and some disadvantages...the OP didn't really state what his intended purpose was (and his profile is very thin), so we're left guessing. I'm just giving him another option.

Even though I have an 8.8 LSD at the moment, I would rather have a rear locker. I don't want clutches in my rear LSD that may wear out/require maintenance/replacement.

If I was going to go to a locker, I'd probably buy a Detroit (which would require gear setup, BTW) for just a little more than the lunchbox locker. I'd love to have a selectable OX or ARB, but they are pricey!

Although I would love to have gotten an ARB instead, I just could not justify the $$$$. When you add it all up they're close to $1200, maybe?

At least - probably $1500 with the compressor.

This is incorrect information - the Powertrax lunchbox locker that I referenced above is specifically FOR the 8.8 LSD carrier. It's the only one that I know of, but there is one...

Not sure how new that product is, but I see you are correct... However it looks like the part # you posted is for the F150.

This looks like the Explorer 8.8
