8.8 4.10 from open to LSD ....can I do this?


One of my former techs put a Lock Rite in his 97 Ranger 2wd. I got him up his driveway during mud season but sounded like it was grinding itself to death when he turned in the driveway. He said it also wanted to slide around on snowy or wet roads.
How do you use the truck? Heavy duty off roading might make the Lock Rite a better choice and the Traction Lok would be easier to live with on the street.

So… I’ve had a lock-right in my F-150 for like 10+ years now and yes, it likes to make crunchy noises and bangs on the street and has a tendency to want to push you along straight in poor traction situations so I use 4x4 more, but it gets the job done.

That said, I heard something more recently that suggested there is a right and a wrong way to install those lockers and that I think it was Aussie that explained how they are supposed to be shimmed for smooth and relatively quiet operation. I haven’t really investigated it because I’m currently not ready to try and install another one.

A limited slip, especially with bad clutches, will have a tendency to lock up late and give you poor handling. Pack extra clutches in and increase the pre-load spring and now it works more like a locker, but brings in some of the handling characteristics of a locker. It’s all a trade-off. For street use, a limited slip, preferably a gear driven one, is probably the most ideal if you want more traction than an open diff. Or a selectable locker, but those are more expensive than a gear driven limited slip.

My green Ranger is a street toy. I currently have a factory limited slip with new clutches and I packed in extra clutches. It does pretty much exactly what I want it to. Someday it may get a gear driven limited slip. My F-150 has been my workhorse, on and off the pavement plus snow plow duty. A locker of some type is preferable there. Choptop was built for off-roading, but still street driven, so again, lockers. Figure out your needs and budget and go from there.

Mine are quiet because I use 85w140 gear oil. Does great on snowy and wet roads, way better traction than with an open diff.

Well... you can't just leave us hanging here. Got a link to this?

I'm curious... because I'd like to do something to my pick up for better off road chops.

At 133k miles... if i pull it apart to do a carrier... i would have to regear. Then the front diff would also need a gear. While in there... I'd have to do a carrier. That adds up to a solid over my budget price tag. If I go that far I'd rather regear the Bronco II.

I don't think I put more then 10k miles on it in three years. I don't drive much... but it's still my daily. Just around town and a couple longish trips each year. Those trips are exactly why I'd like to have a locker.

A drop in locker would be cost effective... but worried a bit about the manners and the clack... bang... boom when on pavement.

If there is something in set up that helps with that... do share.

I don't recall anything specific to make them quiet. But, Aussie does specify some measurements and making sure you have the right clearances for proper operation. I have the manuals from mine. I can scan and post here tomorrow.
 
shimming a lunchbox is application specific. sometimes you need a different carrier due to normal manufacturing tolerance.

with the dana 60 and spartan never noticed any difference between bottom dollar 80/90 and 85/140. but with the 4 pinion ARB in the 8.8 it was night and day especially in winter. i have to change my oil more then normal due to water exposure so i run cost on the 60.....usually the 140 has been best deal lately. same with the 44 and 9 in the bronco

Here is the installation manual. It does mention on page 4, using 85-140 weight oil in hot weather which will reduce noise levels

My F-150 with the locker does have 85w140 and it’s still noisy… so oil isn’t everything. Glad it worked for you, but it wasn’t my answer.

Unfortunately, I was given the information as word-of-mouth and have not done any searching as of yet. I’m still kind of annoyed that I can pick up a lunchbox locker for under $200 for the Explorer 8.8 but for the Ranger 8.8 it’s over $300 and none of the Explorer axles I have currently have, have a useful gear ratio (3.08 and 3.45 if I remember correctly). Plus I have no extra money to buy a locker anyway right now. So it’s just been a back-of-my-mind kind of thing for now
 
the oil is for the ratchet noise.....ratchet noise isnt a thing with a idi diesel or resonator piped 4.0...

the crash bang, holy shit what was that!!!!....is a tolerance thing amongst carriers .

my ranger goes off like a gunshot... startled me a time or two. i popped the cover expecting problems...and it was fine ....

i could get a different carrier and it might be much more civil...or be stuck on....or not work worth a damn. i just live with it. someday a selectable will be there again.....it will be fine.

f 150.....and jeep guys. that is why there is a difference in price
 
I'm not sure how this one never hit my radar until yesterday.

PowerTrax No Spin. Claims to be a street friendly daily driver locker offering. I'm gonna try to find more reviews before I jump on one. They make them for an 8.8... the 28 spline is more expensive then the 31 spline.

Might just be my Christmas gift. .
 
Anyone have any experience with one of these?
 
yup ... there was one for limited slip carriers and open carriers.


with large tires, 300 or more hp and ridiculous throttle application, they tear the shit out of the carrier. but that usually takes years. fresh crosspin and drop it in a 100 jy axle and off ya go.

problem i had was also case deflection. so i went to full carrier and truss....and a good ARB locker.. then the super ARB. then the super duper ARB.

eventually it was obvious i was running too much weight for the 8.8 and needed a bigger axle.

the bigger axle tolerates alot of my stupidity and the drop ins shortfalls.

for the money and ease of install i love the damn things.

for me, more pro then con.
 
that said .... pj had issues with his....look at his situation
