Hey guys I am trying to gather all the info before I start my build in next few weeks

To Start the specs of my jeep are as follows:

1997 Jeep Cherokee xj
Dana 30 (front)
Dana 35 (rear)
W/ ABS
4.0L

First off,
How do I remove and replace the steering knuckle?
Anything special being that it has ABS?

and What about the Front Hub Assembly?
Anything special?

Thanks in advance

 

Edited for sake of length. I appreciate the effort in your reply. Good info.

Literally, though, the TF999 and 32RH are the same tranny except that the 32RH has electronic lockup. If you have a 32RH that didn't come with that, it's a TF999. Likewise, a TF999 that has it would be a 32RH.

Aside from still disagreeing about that, it looks like my choice of fluid didn't kill my trans. That's always good news.

 

Hello,

I have an AX-15 shifting issue that changes when the jeep is cold vs warm.


When cold
Shifting is normal and smooth through all gears


When warm
Shifting into 3rd requires a slow release of the clutch and some gas to achieve a smooth (but slow) shift. If the clutch is released at a "normal" rate, the engagement is rough/jerky. If the gas is not added, engine rmps drop too far. The throttle helps keep engine rpms at the proper speed and makes for a smoother shift into 3rd.


Any pointer would be greatly appreciated.

 

Is your clutch original?

ABS sensor should be unplugged

 

Not sure why you think we disagree on anything lol. Here's the Pirate thread btw: http://www.pirate4x4.com/forum/jeep-...ifference.html

Souds like you've got some old clutch, old fluid, and maybe a vacuum leak keeping RPM high.

 

Both of you are right on both levels. The RH transmissions are built off of A904 and A999 transmission cases but are electronic valvebodies and lockups. The A904 and A999's are non-electronic fully hydraulic transmissions.

To better explain it, we'll jump to the Chevy camp. Take the TH350 and the TH700R4. Both are built on the same design case except the TH700R4 is electronic with OD to where the TH350 is not.

Yes, fluid type can make a big difference in transmission behavior due to the different blends or additives. A lot of the solenoids and sensors in electronic transmissions are very sensitive/picky to what they'll operate in.

 

I was told the clutch had <10,000 miles on it when I purchased it. I've put another 10,000 on it.

My wife and I both learned how to drive a manual trans during those 10,000, so it has had a harder life than the average clutch's for that mileage.

 

Bumpity bump bump.....RR

 

My throwout bearing started to make a lot of noise right around 170k miles so I replaced the clutch with an advance auto perfection kit. 5k miles later and its hard to shift once it warms up and shutters bad on takeoff. I'm am now in the middle of dropping the ax15 again but this time I'm putting a LUK flywheel and clutch kit in.

If your shifting issue is only one gear, it could perhaps be the synchronizer ring. The original Jeep transmission fluid was not yellow metal friendly and over time the fluid can deteriorate the synchros. Do a google search on ax15 fluid type, there's a lot of discussions on gl3 vs gl5 fluid and how the new specification for ax15 fluid is 10w30 engine oil. Id start with a drain and fill to check for metal, see if anything abnormal comes out and also see if the shifting is better after new fluid. Also with the Jeep off and your feet on the clutch and brake pedal, try shifting through the gears. Any easier?

 

No it's not. Chrysler stopped carrying GL-3. That's all.

 

Threw 2 codes today. P0340 and P1391. Cam sensor condition and CMP or CKP intermittent condition, respectively. I replaced the crankshaft position sensor 8 months ago and put in a new distributor 4 months ago.

Thoughts on if one or both sensors are the issue? Runs fine, with a slight hesitation around 15-20 mph. No other issues. Did not start this hesitation until tonight when the check engine light came thus throwing the codes.

 

Check out post #7 - http://www.jeepforum.com/forum/f12/b...change-865520/


"The Mopar gear oil part number used to be 4897622aa, but when you search that part number you'll see it has been superceded by part number 4761839AC which comes up as 10w-30 motor oil. Here's a link to search the Mopar part numbers.

It's the "new factory spec" lubricant."

 

Yes, however that is not the awful thread that all this nonsense spawns from. I can't find it anymore but there was a whole "Ask A Jeep Engineer" section where fanboys lined up to receive The Word of God.

No. This is a commonly made mistake. Chrysler stopped carrying GL-3 and stocked only 10w30 instead. That is all that has happened. Nothing else. In the original thread, and the bold text which I think is a quote, the rep was very careful to indicate just that. No compatibility admitted, no testing revealed, nothing. Just confirmed what the part number change was.

They are NOT the factory and never have been. Chrysler has absolutely nothing to do with these transmissions other than they bought them and installed them. This is IDENTICAL to how they stopped carrying Dexron III and stocked only ATF+4. Like the decision around the AW4, it was made after warranty ended to simplify dealer stock, not by a team of engineers with your best interests at heart.

Aisin Warner has ONLY specified GL-3 or GL-4 for the AX-15 just like Aisin Warner has ONLY specified Dexron II and III for the AW4.

Chrysler is not to be listened to. They can't even get their FSM right! (one year lists GL-5)
