Yes, I'm the one with the Dana 35...I'm swapping the rear axle to the 8.25 corp. I have an Automatic tranny. http://www.thefergusons.us/kj/kj.htm

The best I can get 4wheel parts and power-trax to do is swap my no-slip for a corp model.

You have to understand how horribly mine reacts while turning, in an effort to save money I am open to the Idea of installing 8.25 corp model no-slip.
I'm only open to the idea because of the off road performance, its a monster.

I would like some real deal feed back of any noise, shifting, snapping, or cracking that you folks with Auto trannys are getting on yours before I do.
I'm really noise and lurch sensative.

I can still sell the new one and install an ARB or Tru-trac

Thanks for the input.

I love the power-trax no-slip. However it does make some noise from time to time and jurk the jeep every now and then, but for me it is nothing I can't live with. I really don't mind it and my fiancée who drives it doesn't really notice it either. However, if you are really noise and lurch sensitive then I would say stay away. It is a not as quite as smooth and silent as spider gears.

When yours makes noise, can you here it from 2 blocks away like mine.

Thanks for the input

Sometimes it can make quite a pop or crack, but most of the time it is just a faint click that is barely audible and you have to be listening carefully(no radio) to hear.

I installed the Powertrax no-slip a year ago. I did it myself and it wasn't too hard. i used the 75W-140 synthetic and did not use an additive. It was a little noiser for the first couple weeks. It still makes the occaisonal snap clack or pop. The noise is enough to make passengers ask what was that? It is not loud enough to turn heads of people nearby. I also have not noticed any undo tire wear but try to keep my foot out of it in turns. i would definitely do it again as it makes a real difference offroad. If I lived somewhere that got a lot of ice on the road I might have considered the much more expensive route of a locker that can be disengaged completely (ARB air-locker).

Mine behave just like this.

Thanks, Keep it coming

Can you feel it in addition to hearing it?

i just bought a power trax no slip i have not put it in yet but i cant wait so we can clear up this whole not good for a 5spd thing....

Huh ???

I can say this, after 2 installs and 1 inspection of the device and rear axle, there is yet to be any damage. Maybe I'll just drive it till I break an axle, no matter the noise?

the locker is going to make noise

Why does the locker make noise? I figure I'd just come out and ask! haha

the design of the no-slip locker allows for an automatic disengagement of the "locked" status whenever it senses a difference in rotation between the left and right wheel....this allows the axles to operate smoothly and essentially quietly during on-pavement use...you can override this disengagement by applying throttle and therefore maintain your locked state...your tires will chirp and hop a little during a turn...

in order for this design to work, there is some inherent "slop" built in to the design which can be noticed in situations such as stop and go traffic where you are constantly on the brake, then a small acceleration, then on the brake, etc...you can sometimes feel a small "clunk" in the driveline....almost as if you had a loose universal joint in the drive shaft...

sometimes when turning, the mechanical disengagement fails to operate as designed....this creates a axle bind which strains the engaging teeth in the locker....this strain eventually overwhelms the design and a loud bang can be heard when the locker teeth slip back into their natural position....

when you are holding the various pieces of the uninstalled no-slip locker in you hands, they don't appear to be very substantial in size or strength....using the "weak link in a chain" analogy, I don't know what would be the most likely failure point in the rear drive train design....my guess would be the ratcheting teeth of the locker before the axle shafts or drive shaft u-joints....the compromise you make with the no-slip product is that its affordable and can be installed without needing to reset your ring gear/pinion gear tolerances...

my philosphy is as with most aspects of four-wheeling, there is the possiblity of mechanical breakdown just down the trail whether you run stock or modified...please bear in mind that I'm just shade-tree qualified to comment here...

Camper,

You should be working for Powertrax. You have the best explainations of all. This is most especially my problem on a several time a day basis

"sometimes when turning, the mechanical disengagement fails to operate as designed....this creates a axle bind which strains the engaging teeth in the locker....this strain eventually overwhelms the design and a loud bang can be heard when the locker teeth slip back into their natural position.... "

My thread was to find out if this problem is of much concern to 8.25 axle owners.

Thanks

mr. jferg...well I like mine ok...

I had the factory trac-loc limited slip....I really didn't know much about any of this topic until I started reading the stuff on this forum last year....I decided to swap out for the power-trax no-slip even though the factory set-up was essentially new....I wanted to do it myself to learn and to save money....it was a challenge because I didn't know that the clutch packs from the trac-loc would make it difficult to disassemble the differential....

I ended up removing the entire carrier from the pumpkin so I could knock the stock differential gears out...I put it all back together and was able to drive it without noticing any problems...but I had a jeep guy reset my ring gear lash a few days later just to make sure....I'm pretty sure he did a good job but since I didn't do that myself, I'll always wonder if its set as perfectly as I would have done it myself...

but the new locker has worked well as far as I know....there are no issues that aggravate me as far as driving around town, etc...every once in awhile it will bang but that's rare...I've been on a few jeep trails with it....drove it out west last spring...lots of guys on this site are running it and I haven't read any bad reviews....

if this thing ever fails, I don't have the original limited slip pieces anymore to put back in...so I'd have to either replace the no-slip or try something else....

I like this jeep web site but you have to wade though the chatter to find the useful information....I wait for the smarter or more experienced folks to throw stuff up here regarding what we can do to the jeep that works....I've been waiting for someone to put the detroit locker (not the truetrac) in the rear and describe how that works for them....

(aren't you in the gulfcoast area?....good luck with the weather...)

camper - you spoke of the strength (or perhaps lack of strength?) of the Powertrax. I'm wondering if air lockers are stronger. Is the extrea money going for a stronger locker?

They are both very strong, air is more civilized. If the no-slip works as (quiet) in 8.25 as most of the reviews I've read, it would be a good choice...traction all the time.

You'll break an axle before you break these devices.

i would spend the extra on the air locker due to it being the easyest to drive everyday because when it is not set the kj will drive like an open rear. plus if you are out on a trail and making a sharp turn in the mud the no slip will cut out cuz you are turning

Good Idea

Yes it will engage/disengage...just like that.
