M/T?? ticking under acceleration while cold

After searching I found lots of "my transmission is ticking" but nothing that deals with my issue.

I have an 08 with 59,000 miles. When chilly outside and I first start driving I get a ticking noise from under my Jeep, it seems to come from the rear of the motor or the transmission area. I can't hear it from inside the Jeep just if I have my window cracked and am listening for it. It only appears to happen for the first few minutes of driving until things start warming it. If I accelerate slowly, no noise, but if I get into it a touch through the lower part of the power band I get a little ticking noise though each gear.

Just wondering if I am alone or if anyone has had this issue before and possible things to eliminate before taking it in.

All help is appreciated. Thanks!

Stock shafts with your 3" lift? Check and see if the front shaft boot on the spline has slipped out from the retainer. The retainer will slide toward the diff in the front if it has. Ticks when the shaft spins... ask me how I know.

I will check the U-joints and shaft boot! As far as the exhaust leak, would I be able to replicate it when I'm in neutral by revving the motor some? Air pressure is 30-32 and it happens whenever the Jeep has been sitting over night or for a few hours and is normally gone within the first mile of driving.

Finally got a chance to crawl under and look around. It appears the front drive shaft is leaking grease, its the end by the TC. It does not appear the boot is ripped but the grease is leaking from around the entire shaft. I assume this is what is causing the clicking. What are my options? New shaft or can the joint be rebuilt?

You can completely rebuild a stock driveshaft. I don't know best place to get all the parts, but guys in my club have done it. You can also buy a new one. Mopar direct replacement is 700. I just put in a Tom Woods. $450. With the aftermarket shafts, you can increase lift in the future with out having to worry about the shaft. Higher than 3" and the stock will be useless. Dont know your plans though.

All great info! Thanks guys, after thinking about it I have decided I will upgrade with a new DS from either Tom Woods or Coast. I just need to research the brands. I will never go higher than 3 inches the biggest I will ever go in tires is 37's after I upgrade the front axle if time and pocketbook allow, but if I am not looking to replace another driveshaft in the future...

Thanks again for all the help and I hope this gives someone else the info the need in the future!

They are junk u joints though. Make sure you specify quality spicer u joints. I could have saved myself a big hassle and cost if I did that the first time.

I'd test drive without the shaft to see if that's the noise. But first, I seem to recall folks talking about the gear shift knob or some such ticking? Anyone?
