So I just got rid of a low speed driveline vibration today, and in doing so I had my Jeep parked on the side of my house where the ground is level. I get everything buttoned up, and I start my Jeep up and I immediately begin hearing angry birds chirping.

My first thought was great, I have yet a new problem - the angry bird / sparrows issue that others have had. Then, I start trying to recall what the angry sparrows problem actually was and remebered that it involved ujoints. Well, I got out of my Jeep and sure enough - it was literally angry sparrows - nested in the crawlspace of my house. I guess the sound of my engine starting scared the shit out of them, perfect timing to fool me into thinking there was a problem...

 
Haha, too funny! If this were real, all the anti-2005 guys would be telling you, "I told ya so"!

Not going anywhere. The "angry sparrow" sound is associated with the centering ball portion of the front Double Cardan joint at the t-case and is common to all TJ's.

I think @Chris was referring to the OPDA which has been hashed and argued here many times.
 
What is there to argue about? They go out, you replace them and go on.

I think the argument came about because a number of people were saying they would avoid 2005 TJs altogether because the OPDA issue is one that is too big to ignore.

I personally believe that like anything else mechanical, if it goes bad, you replace it and move on.

Regardless, funny story...Jeep owner paranoia.

7yrs old traveling across a couple states with my mother and 3 older siblings (Matador station wagon, the vary back was my space) I started making a repetitive sound. My poor mother screamed "Shut up everyone"... I continued the sound until my laughter ratted me out.

I have absolute trust in Blaine's knowledge.

Engines are mysterious to some (Including myself). Arguments I've read (Early days of failures) on different forums revolved around reliability concerns. I thought at one time steering stabilizers curred death wobble!... I know better now.

Back in the day I could listing to a data circuit and tell you it's speed. build a field network (Limited speed) without a switch. (Rx+,Rx-,Tx+, Tx-)
or tear down, rebuild a StrataCom in under 2 hrs. Useless skills today...

Come on guys, get your sounds straight! Lol!
Ahh yes! The bad OPDA is indeed the primary angry sparrows sound. Someone had described a bad ujoint / centerball also as angry sparrows on a thread somewhere that I read recently, so I got my wires crossed o.O
 
Angry sparrows always meant front drive shaft issues to me.
Considering it has been in use since a couple years or so after the TJ was introduced, I think that it's accurate. I had the bushing at the top of the shaft on the distributor in my 99 go out at about 25,000 miles. Never gave it a second thought, just bought a new one, installed it and went on.

Are folks more skeered of the OPDA issue or the 0331 head? Given the disdain I see for the plastic tanks on the radiators, I'd figure no one would want to even own a TJ.

Haha, no shit! I'll admit though, that was one of the first things that I noticed when I popped the hood open on a TJ. I had even thought briefly about replacing it with something "not plastic", but hey - it's lighter!
