Hello,
I have a 98 XJ, AW4, 342k.
I need to replace the speedometer gear, as well as the drive gear (in the tail housing of the trans). For this I need to remove the tail housing; Can this be done without dropping the transmission?
I have had trans codes for a while but a P0500 lately and the speedometer started acting up and stopped working at times. I removed the Vehicle speed sensor and the adaptor and saw that the gear is completely chewed up - that's easy to replace - but the drive gear, located on the output shaft if broken.
Thank you.
Marc

 

No need to drop the t-case or the tranny.

 

Thank you. And it is a 2WD. So I'll just need to remove the drive shaft, and then unbolt the extension housing, correct?

 

Yep.
Male sure you put the rear axle on jackstands so you can rotate the driveshaft, makes removing the straps a little easier.

 

Great. Thank you for the tip.

 

You're welcome and good luck!

 

Upon reasembly make sure you clock the gear correctly.

 

Yes, i figured that out after i put the sensor adaptor back in.. No big deal since the gear drive is broken anyway. i am out of speedometer for now but i will have all the parts i need by mid next week and do the job next weekend.
Thanks all for the info. I'll post results.
