Rebuilt engine? 3 yr warranty? What should I expect the cost to be? For its age 10 yrs pretty low miles@ 130,000

Dealership here quoted $500 to repair both front half axles. Trying to figure out if that is toward the high end or the low end . Page on repair pal said $280-$534, but I wasn't sure whether that price was for one half axle or both.
Thank you

Boots at both ends of axle appear intact, no obvious rusting/damage of suspension components, no leakage visible.

Especially in cooler weather. Now getting worse ie. 3-4 and a harder clunk. Had software rebooted. No help. Progressively worse over 3 years. Noise stops after a mile or two.Sensor? Torque? Tranny?

cleaned maf sensor and light still on.

dealer price 1400 dollars is that a good price?
