when i engage 4x4

[llamaking122]

there is a loud humming. really loud the 4x4 works and i just cleaned the auto hubs out. also there is a pulsating in my steering wheel

Also when my ex has been sitting for a day or so i back out and i put it in drive and when the front end flexes from hitting the gas i hear a pop.

im doing o2 sensors and plugs and wires. what are some tips to get teh o2 sensors some people say theyre hard too get out. i have already read about getting that last plug. im getting 8-9 mpg soo i have to do this LOL

btw its a 1994 explorer limited

The humming may be from old diff fluid. When was the last time it was changed?

The pop is probably a worn out radius arm bushing.

If you don't have a torch to heat up the area before breaking the O2 sensor lose you should run the engine to warm up the exhaust. Just be careful not to burn yourself.
They make a special O2 sensor socket, it's worth the $5-10 since it makes it easy to add a breaker bar and cheater pipe.

yeah i have the socket from past O2 sensor replacement. and i have an impact but no torch at this time to i might get a propane tank one that has the heating tip

also one of the fig lights on mine had water in the light so the internals rusted out. and i dont want to pay $80 for a replacement what can i do i would like too utilize the stock foglamp holes

I'm sure you could find some after-market round fog lamps for less than 80 dollars. Ones that will also fit into the stock mounting holes as well.

Edit: Check on JCwhitney or Autobarn

the problem is that i need ones that mount in the back. but i might end up making a bracket. i can get GROTE stuff for cost so i know i can get it cheap
