I'm only imputting for those who are in the med range of off roading (6"-33"s) and on a buget.
When choosing my new dream XJ I searched for the 242.Fulltime is great for rain and snow.
My 87(242) has had 6" lift for 14 years/320,000 miles.I replaced the tailcone seal one time.No SYE and only added a longer slip yoke from MJ.
Sye setup is smoother than stock, it's true.
My New(Stock) 2000 had vibes at 50mph and over and after switching 87's lift and axles across to the 2000, it got real bad.
I urge anyone with vibes to check the output shafts of the t-case for runnout.Take shafts off and run in gear.I found the bent tailshaft when cutting it off. Finished H-n-t but still had vibes.
Kid must have slammed it cause it had No undercarriage damage from offroading.
I've been a toolmaker for 24 :bs:years and design and build manufacturing tooling for commercial jetliners.I spent 5 years OD grinding turban shafts and fitting impellers on splines for train locomotive turbo's(18,000rpm).
I just did the H-n-T on the new tailshaft "the best way" at work on a lathe.(perfect)Doing it under the jeep was a bitch and with the tailshaft runnout, I had to stop the engine and just cut it off.
If it runs true you'll get it done. 1.250 of spline should remain.
See my tool I made for drilling and taping when under the jeep.
Will loan if you'll give it back.RE tells of making guide in kit, out of slip yoke,(it will be Needed).
No offense to TW's but the cutting down of the shaft and resplining is a bunch of crap.That is just to make you happy with your favorite yoke style and ruin's the tailshaft.:gag:The shaft is factory case hardend and will twist or bent easy after removing the O.D. even if they hit it with a torch to heat treat it.(Its not the same).They have vastly more experince with that than I do.:dunce: Yes,They do.They are offering something that otherwise would not be avalible,so it is- what it is.
The factory splines are very consistent.My RE flange slid on the tailshaft after cleaning with a light press fit(no slop at all).The RE part is cnc machined and is of high quality stainless steel.This is not a bandade.
If you install it right it should not loosen up.
My 320,000 mile slip yoke is still snug so why would a locked down perfect fit spline fail?
If your slip yoke was worn and vibrating causing you to want a SYE then you have to add up all the reasons for problems.Rebuild your driveshaft with new u-joints and get your axle at the right angle.
As far as the older seal type go's maybe your output bearing is shot or shaft bent to cause leaks.My 87 with 320,000 and 2000 84,000 miles have no (t-case) leaks.Yes they have fliud.
? other than the speedometer sensor being elec. is the Lg tailcone the same and could you just switch to the newer sealed model?
Keep it simple----Let the $13 u-joint break and bring a extra set of drive shafts.
Just my opinion.
To GoJeep,Are you the same guy with the cool jeep website?
Thanks for all the Info and your yoke setup was my first choice but just had hard time finding all the parts for cheap.
