OK. There seems to be some disagreement as to if auto lockers will allow my 242 to function, so I thought Id do fluid changes and kinda prepare for some future mod to the diffs. Now the dumb question: when we talk about spline count exactly what are we counting, teeth on the input shaft or something else?
Thanks for help

Use the brake and the gas at same time. Works wonders!

No disagreement, just understanding. An auto locker will make using Full-Time on the street/rain/snow obsolete. That is what FullTime is for. PartTime is for offroad.
Spline count in axles is the axle shafts, where they mate to the carrier (differential).

 

Not at all. SteveMongr said what I've been trying to get at. If you go the auto-locker route, the Full Time feature will be no different from Part Time. If you don't care about the Full Time 4WD (which is also called AWD) then it doesn't matter.

As far as gear ratios go you need to buy the correct locker for your axle. In this case you'd want one manufactured for 3.55:1 and lower.

Start with a standard tune up. Who knows how old the spark plugs and wires are, O2 sensor is, how many vacuum leaks you have, etc. Simple things first.

As stated the 242 will work continue to work in general, but the biggest feature (Full Time/AWD) just won't do anything "different" with an auto locker.

Again, "spline count" depends on context. There are different versions of the Chrysler 8.25" rear axle, upgrade shafts to the Dana 30, input gear to the transfer case, and so on. It's kind of like going to a doctor and saying "Muscle Pain". Where? lol

 

Now I'm confused ... (not that I'm looking for a locker but just want to learn)


Are you saying that full time can not be used on the street anymore after installing a rear auto locker, or that it just won't do much good because the front end can still spin ???

 

Almost.

With a locked front end in Full Time 4WD on slippery/loose surfaces you get massive understeer with the added bonus of if a rear tire loses traction, you're not going anywhere because the diff in the transfer case will send all available power to the rear wheel. It's just useless. The main advantage of 4WD Full Time is to have differential action up front so that you can keep traction while driving on semi-loose or variable surfaces, like snowy roads or ice.

The same issue would happen if you locked the rear axle and used 4WD Full Time, but you wouldn't have the same understeer problem.

But, if you don't give a **** about driving on ice, just run it in Part Time and be happy.

 

It is the front axle that causes issues when locked, on street, or ice-snow, using FullTime.
Bad on street due to binding/chirping/understeer. Bad on snow/ice because turning with throttle, will cause a front wheel to skip and loose traction.
And of course what Salad replied also!

 

Okay, so a front locker is basically no good at all for a street vehicle that may be driven in snow, etc.

 

A front *AUTO* locker, right. It definitely requires special handling. A limited slip or a selectable locker - which is a differential unless you set it otherwise - does not have this issue.

 

My 2000 sport 4.0 L6 motor's camshaft syncro seized. Ripped a few teeth off of the camshaft. Obviously I need to replace the camshaft. Just a quick question before I tear into it. Do I have to remove the head to remove the lifters? Before I get dirty, I want to know how dirty. This will also give me an idea how clean I will have to get also.

 

As far as I know, yes.

 

Where can i get a shroud to cover the metal radiator fan?

Has one on the electric fan but the metal fan is exposed

Also where can i get a oem speaker cover for the front speakers?

speaker covers are junkyard

 

So if I put a limited slip diff instead of an automatic one in the front axle would solve the problem,right?

And do i need to take into consideration gear ratios even if I keep the standard ring and pinion?
I mean when I buy the limited slip diff, does the gear ratio has to match my standard one?
( because I need to find what that is as standard)
If mine came as stock with 3.55:1 ( as told by Salad) I need to get a diff with gear ratios up to 3.55:1.
Am I right?

 

Lol. It's not a "problem". All I'm saying is that if you like Full Time 4WD... It won't work the same anymore. If you don't care, then don't worry. Hopefully that is clear enough.

Yes. In the Dana 30 the differential carrier that the gears physically install to are different sizes. 3.73:1 and up ring is taller. 3.551 and lower gears will not install into a carrier of that size.

 

Thanks Larry's XJ. I was afraid of that. Didn't want to get that intimate with my motor, but.
Well, according to the time book it's supposed to take ten hours, or at least that's what a shop would charge @ $90.00 t0 $100.00 an hour. There's $1000.00 I will save and not being a novice, should only take me two weeks to get her back on line. If anyone knows anything special I should know, I would appreciate the input.
