Question about 2005 Subaru Outback
When driving our outback we get a medium thumping noise toward the rear and more to the passenger side. The speed of the thump goes up with the speed of the car (not with the accelerator exactly). It makes a sound as if something were caught in the drive axle and was spinning around and bumping. A friend told us to lubricate the differential, and I am medium-handy so perhaps I could do it myself if were worth my time.

Check the rear differential mounting bushings there are two at the rear of the differential, instead of full solid rubber bushings they have open spots on the upper and lower areas of the bushings causeing them to break causing the differential hop up and down making a thumping noise (seams like their made to fail), I've come across this a few times, not a cheap repair, I found a quick and easy way to remity this, I rise the differential until there's no gap at the top of the bushings clean the lower openings then cut a piece of 5/8s heater hose about an inch long coat the openings and the outer hose with silicone sealer and push it in the openings then lower the differential and repeat the same on the upper openings let dry for at least 24 hrs. Hope this helps.

Start with inspecting the rear tires for out of round or bulges.
Next, inspect the rear shocks for oil leaks,
Both of these can cause the thump you describe.

its probably your bump stops. the vw ones are very soft. i bought ford escort (the shape after the xr3) ones and cut them a little down to fit. i think the noise is either your shock touching or the sound of the tire scraping the body of the car. hope this helps.

I have the 03 Expy with continuous rear air unit "clicking" or more accurately flapping of the air damper while the plastic gears in the 2L2H-19E616-AA grind away into toothlessness. Ford designed this unit to find the end of travel by jamming the motor to a stop and monitoring the current to determine when to stop applying voltage. That would probably be fine if the gears were designed to handle the jammed torque or the motor did not slip out of groove and continue turning and cracking the plastic gears.
There are two white colored boxes, one is for the temp plenum door, the other the upper/lower air flow. To be sure, do what I did, turn on the ignition, rear ac/heat and listen for the obnoxious click/thump as you move the temp control from full heat to full cool, you will know which part. Disconnect the electrical connector, four bolts and it is out!
Go to your dealer, part should be about $60 or less, look on line, lots of dealers sell for this or less on internet.

If I understand you correctly, you feel a vibration it the brake pedal when you apply the brakes. Is that correct?
Have your brake rotors re surfaced; they are warped.
"engine makes cavitating noise" ....what does this mean?
