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?
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
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).
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.
