Post Driveshaft Spins in Neutral on Jacks

Hey guys,
I took my 06 TJ in for new brakes and the mechanic told me just as an FYI that my front drive shafts turns while lifted in the air and it wasn't normal. He continued to point out that the noise it made sounded like the wheel on "Wheel of Fortune".....basically he spun the tire while on the lift and clearly you could see the front drive shaft spinning while making the tick tick tick noise.
He sad the gears were going bad and that I had Transfer Case issues. Any help or guidance on this would be great.

Is this a serious issue?
Cost to fix?
Any suggestive repairs to be done simultaneously?

You mechanic is incorrect, it is normal for the wheels and driveshaft to spin in 2wd and is unrelated to the clicking issue.

When in 2wd, the front driveshaft is disconnected in the transfer case but stays connected at the axle side. This means when you turn the wheel, the driveshaft will turn as well. Perfectly normal. It only wouldn't spin if the transfer case was in the 4wd position. A clicking sound however isn't normal but I would take it to a more competent mechanic to get that checked out

Call the mechanic and tell him to find another profession, then find another mechanic.

We shouldn't be so hard on the mechanic... It was very common on CJ's to have locking hubs and in this case, it is possible for the wheels to turn without turning the driveshaft. He could have just been thinking of CJ's and made a mistake.

Still, there would be nothing "wrong" with your axle or transfer case even if you had locking hubs and the wheels turned with the driveshaft (assuming the hubs were in the locked position).

Kinda but not exactly with fixed hubs and tc in 2wd if both front wheels jacked up if you hand spin one wheel the front driveshaft may or may not turn

If you have a stock open differential when you spin one tire the other wheel can turn the opposite way at the same speed and the driveshaft remain still

Or one wheel can turn with the drive shaft spinning at the rpm of the wheel times the gear ratio

Or some of each

I don't know what happened or what was clicking and neither do the other posters we only have your limited expression of what was observed

Before you decide a poster without the direct observations or full story knows the guy you went to was wrong get more data

Could the mechanic have found a prob maybe could he be full of it maybe but there is not enough here to draw a firm conclusion

Run from the ready fire then aim crowd

If the tc was in 4wd and with only front wheels off the ground then he is correct front drive shaft should not turn and if it does with tc in 4wd back wheels on ground the tc chain could be stretched and jumping over cog teeth making a clicking sound

Again you need more specific data before reaching a conclusion

Hey guys thanks for the input. Your all right I should certainly find a good mechanic. Im trying to learn as much as possible as this is my first rig. As far as the ticking noise, I really think its just the rotation of the drive shaft. I'm hearing it though the drain plugs and its really faint. Again it could be faint because of the tires and all of the other surrounding noises. Overall I think I'm good to go. Thanks again for everyones input.

Assume the guy is incompetent based on an incomplete 2nd hand partial story. Aiming requires some situational awareness and at least asking the right questions before coming to a conclusion.

Make sure it is not the chain in the transfer case slapping the side of the transfer case

That chain is spinning whenever the front wheels/drive shaft turns so all the time and a loose steel chain slapping an aluminum case guess which wears thru
