aww shit i do have it. but i can select 2wd only. do i have to get the driveshaft or is that only if i drive in auto over 35mph?

 

[SunlitComet]

If you four wheel you need it. if your drive more then 35 mph or what ever it was regularly you also need the new shaft.

You will get a nasty vibration without it. You can run with the shaft off...like you will need to do once the lift is on and until the Y pipe get modified to run around the shaft

hmm... don't remember reading about a y-pipe mod in the RCX lift instructions.

What's different with the replaced front drive shaft? What do I need to look for when I buy one?

You need a CV front shaft. It has a double U joint at the top. If you are running a stock Y pipe it needs to be cut and routed around the front drive shaft. When you lower the front differential the drive shaft wants to be right in the middle of the pipe

Corey, you WILL NEED the Double Cardan U joint front Driveshaft!!! I didnt have one in mine and I damaged the front output shaft bearing in my Tcase!! As far as all Escalades go, they ALL came with the NP246 Auto Trac Tcase!! And that front driveshaft ALWAYS spins regardless if in 2HI or 4HI, because thats what enables you to shift into 2HI to 4HI while moving up to 50 MPH and the Auto feature all it does is lock the fron actuator and apply clutch pressure to the front DS when the TCCM senses slip in the rear wheels. I dont suggest running in auto 4WD because of worse gas mileage and more wear in the clutches.

I ended getting a good used Double cardan DS on craigslist, so just search!! In the meanwhile run without the DS until you find one if not risk damaging the Tcase!!!

yea im sticking with my original not to lift it. the more i look into it the more i dont want to. not to mention i really dont want to rust my truck driving it on the beach. So looks like for the price of a lift im gonna pick up a beater beach rig

 

[99Yukon_Z71]

I drive my truck on the beach all the time, just dont drive in the water!!!! And after you do some sand playing, wash your truck completely!!!! No rust on mine!!!
