Topic: transfer case drop question????

[dan684]

is a transfer case drop completely necessary with a 4"lift?  the drive shafts are almost straight on flat ground.  i know this changes on the trails but i nee some ground clearance.  sometimes when i try to climb over something the t-case skid draggs and the 1 inch seems like it doesnt meke much diff in angle of DS
thoughts?

if your shafts are ok and you have no vibration out of them then you should be ok.  just make sure they are not binding up or you'll go u-joints fast.

I've never seen a 2.5L  YJ get by without either a SYE or a TC drop with a 4" lift.  Check your rear slipyoke and see how far out from stock it is (the slipyoke will be shiny where it used to be inside the tailcone).

You'll also want to check the angle of both rear ujoints, making sure they're the same angle (pinion and tc output parallel) and within proper operating range.

well i have a 1"tc drop now.  just wondering if i could remove it for some much needed ground clearacne because i dont want to go ove 33 tires until i can get my hands on some axles.

Like it was said up above, I don't know how you can get by WITHOUT it unless you do an SYE/drive shaft conversion without bad vibes and/or wearing everything down real fast.

I agree with the rest...  Angles are important and driveline vibrations are greatly enhanced are those extreme angles...

But the mention of slip is just as important.  The last thing anyone needs is the driveline spitting out of the output shaft of the T/C at speed (under load) or during don fun articulation.
