Intermittent Chirping Noise

Intermittent Chirping Noise
2004 Disco - Recently replaced the engine when truck had 122k on it. It also has new terrafirma shocks, springs, 2 inch lift, brakes, rotors. drive shaft and tires. I have noticed since getting the larger tires (could be a coincidence) the vehicle chirps intermittently as it is in motion. It seems more pronounced on the passenger side and when I am driving slowly in a neighborhood. It almost seems like it happens as it goes over bumps but I am unable to replicate it by pushing on the bumpers. The chirping does not increase with acceleration.
Any thoughts on what to check?

Pushing on the bumper only does so much because your weight doesn't really compare to the forces it sees when driving. One way to test it is to jack the vehicle off the ground and use a long 2x4 as a lever under the tire to force it up and work the suspension. Use jack stands.

As in how and where it was driven, and in what climate.
My 04 also has 122k miles, and mine drove well with no noises(other than engine tick).
So far so good...but it is a LR...everything breaks and wears out faster than most vehicles.

After chasing this chirp all over the place, it turns out the rear drive shaft was the culprit. I had tried to grease the zerk last week but it was clogged. Finally got around to pulling it off and cleaning it out. Reattached and pumped the shaft with grease. Quick test ride confirmed the chirping is gone!!!

Spoke too soon. Looks like there are multiple sources. Rear drive shaft was a contributor as it looks like it was never greased. But I still have a noise on the front right (I think) when I hit a speed bump or pothole.
Going to try out Jason’s suggestion with the 2x4 and see if I can isolate it.

Problems Resolved
The last squeak (which was turning into a clunk) turned out to be one of the shocks coming loose in the rear passenger side. I tightened it up and went around and tightened all the others. So in review, I had 4 separate sources contributing to squeak ands chirps:
thanks for all the help and guidance!
- idler pulleys bad
- exhaust leaks
- rear driveshaft not lubricated
- rear shock coming loose.
