So i have the 8.8 rear end with the 3.55 gears and factory limited slip and when I was goin on some trails today i got stuck and only the back right tire spun while the back left tire was sitting on perfectly solid ground. Is replacing the clutch pads in the diff hard? are you required to remove the diff to change the clutch pads?

 

I have had this same problem and it seems like if you give it alot of gas when your stuck it will just turn your free tire, but if you brake then let off and give it just a little gas...your limited slip should grab after doing this a few times. What kind of truck do you have, is it 4x4, and how many miles?

 

no it is 2wd and thats why i need it so bad lol. Also i have 195K miles on it and I read today that generally the limited slip is good for about 20k. I am planning on replacing the clutch packs next weekend but i am unsure if the aftermarket, carbon fiber clutch packs are any better then the stock ones or if they will last longer

 

Buy yourself a PowerTrax made by Richmond Gear and you will be very pleased. I put one on a 2WD Chevy Silverado once and could not believe the difference it made. It's basically an automatic locker and it's relatively cheap. Probably less than the rebuild on your stocker. Do a web search for "PowerTrax" and it will take you to the site and they have videos on how it works. Also pretty easy to install. Except for turns and curves it locks both wheels together and it really works better than any LSD.

I was actually looking at those today! the only problem i see is that i drive around town alot and my tires already wear out in 1 year. If i have a locker wont they wear out faster? the reason i was looking at LS was because it will cost 60 bucks to fix and just a couple hours

 

Actually, no. The unit is designed with synchros similar to a transmission. When you go around a corner or curve the unit allows the wheels to travel at different speeds. I did experience a little tire chirp once in a while if I tried to accelerate around a turn, but normally, I never heard a thing. I didn't notice any excess tire wear. Check out their web site. It has alot of technical info on how it works. If you have anymore questions, feel free to ask and if I can answer them, I will. Good Luck.

as i am looking for this locker i have to choose weather i have
Ford 8.8" 31t TracLok 3/4" shaft
or
Ford 8.8" 31t TracLok 7/8" shaft
How can i tell?

 

That I'm not sure about. Can anyone help?

 

Is that the size of your axle shaft? You might have to pull out an axle and measure it, or your rear end code might tell you...

 

Would i be able to see from the H9 axle code on my door jam or do i look at a different code somewhere else?

 

if you are looking at the PDF file on powertrax site. Its not correct. Its states that the front axle in a 2000 F150 is a DANA 44 IFS which is not correct its an 8.8 so id try find info out else where,

ill continue to do to look for you.

 

alright so i got a pretty hefty ticket today hunting where i shouldnt have been so for now the powertrax is out of the question, I am just going to replace the clutch packs for now. If anybody cares to see i can take pics of the process so others might be able to do it easier

 

ckyuv,

Sorry to hear about the ticket. That sucks. I know that the clutch packs are probably going to be alot less than the Power Trax, but the reason I was suggesting it was because I've read alot about the Ford LSD and from I gather even in new condition, it doesn't do much of anything. I may be wrong, but that's what I hear. I have open diffs on my Scab, so I can't say for sure. Maybe someone here can give you first hand info from actual experience. Hope everything works out for you.

i was wondering the same thing, i have like 160,000 miles in my 00 f150 7700 with the 10.5'' rear end, and i noticed that it just dont hook up like it used to i would imagine you would probably want a shop to put those clutches in since they have specia guages to measure the backlash in the diff after they reasemble it, there are shimms and if you dont line up the diff just perfect you will get a good whine or even blow up your diff going down the road, am i right?

 

yeah pretty much, you dont have to worry about backlash tho if you do not remove the pinion gear as far as i know. The only thing you need is something to measure the thickness of the clutch pack. I could be wrong tho so dont hold me to it
