Front drive shaft spitting grease

So my front drive shaft CV at the transfer case is spitting grease but the boot is intact. What could be the issue?

Did you check the whole circumference of the boot. They usually fail in one small section first. Then they open up fully later.

There’s a split. You just can’t see it. Maybe needs centripetal force to open, maybe use your fingers, but whether you see it or not-
replace that joint ASAP!

I was on my way to Florida and camped in Talladega National Forest and decided to check the driveline after about a 5 hour drive on paved backroads and some gravel forest service roads. Prior to departing, I had checked the CV boots and no grease was observed. Most driving was below 55 mph. Upon inspection after arrival at the campsite, I observed the grease that was swung out of the transfer case side CV. I decided to limp back home ( about 115 miles ) that evening thinking that traffic was minimal at night so I could drive slow. I was able to make it home driving no faster than 40 mph and stopped about every 10 miles to check on the CV. This morning I dropped it off at Regal here and asked them to remove the Eibach lift and replace the front prop shaft to improve reliability - one of the reasons I bought it.

@jvkintheusa doesn't that mean you'll have to replace the entire axle? wouldnt it be easier to just go the terraflex route regardless if you keep the lift or not?

I have a spare driveshaft so I'll pay for labor and it's under warranty. I could have replaced it in the field but since the boot still appeared to be intact and wasn't running hot, I decided to limp home instead. I'll keep the one they take off and I will rebuilt that one with a new Teraflex cv and keep as a spare. I probably could do the swap myself including putting on the oem springs but what appears to be simple never is.

Got the result from my failed CV from Ineos today. Looks like the previous owner did not have the Teraflex CV replacement installed correctly.

Missing the circlip? That sounds like it was lucky to make 10 miles let alone whatever you put on it! Unless they mean a different one?

Make sure you keep your old shaft.

Yep, going to put a new CV on and use it as a spare.

Can you be sure to get your old CV and boot. I'd like you to cut the boot for inspection.

Could you elaborate on how to evaluate the temperature of the transfer case CV joint?

If your finger tips go "ssss" it's too hot.
