Hello everyone,
I have been browsing through alot these threads and have learned quite a bit already, I just wanted to see if anyone could help me out with a few things with the ranger I just bought.

-There is a wuh wuh sound which seems to be coming from the front end. I hear it most up to around 15-30 mph. Steering doesn't affect the noise whatsoever so i figure i can rule out a bad wheel bearing. i plan to take a look at it tomorrow. Just wondering if there were any common issues..

-I have the "bump" from taking off from a dead stop, and occasionally i notice it when im braking just before i come to a stop. The truck shifts fine so im pretty sure its not the trans. i bought some normal lithium grease from advanced and have learned to grease the slip yoke. I plan to grease it tomorrow. its a 2wd just wondering if there was anything i should lookout for before hand or any tips/tricks..

-The compressor on this thing. It seems to come on every 10-25 secs no matter if its heat or ac. I asked around and was told it was most likely low refridgerant. Air was already cold as s***, heat was hot as s*** so i wasnt too worried. I attempted to charge it,(while it was like 50* outside) and the compressor kept clicking dropping pressure, clicking again and a second or two later the pressure would gradually build back up. I didnt want to overcharge it so i stopped. Any Help?

-While the truck is idleing there seems to be a very slight stutter/miss. I have no check engine light, doesnt seem to affect anything just annoying. I ran some seafoam through it, hasnt changed any. Aside from changing plugs/wires etc i was wondering if there was any easy common fix for this?

-Last the power steering pump is LOUD! steering is fine,Fluid is good. I read this was common on these trucks so Im not too worried, Aside from changing fluid/vacuuming it i was wondering if there was any secret additive or trick to possible quiet it somehow..

Thank you all for any information in advance..
