Re: 91 explorer
I recently purchased a 91 Ford Explorer 4WD 5 sp and I am really enjoying the vehicle but it is giving me some troubles. I recently replaced the radiator myself and had a mechanic replace the front seal to fix some major coolant leakage. About one week after this was complete, the car has developed a ticking noise that is 1) accleration dependent (ie, the ticking is faster as the car speeds up), 2) not constant, and 3) is sometimes a single tick-tick-tick and at other times is a double tick (almost overlapping). It does not stop after the engine warms up, but like I say it comes and goes.
The previous owner used Mobile 1 synthetic oil. I have a bad feeling that the mechanic I went to for the front seal repair did not use synthetic oil. Could this be the cause? What could this switch do?
Any adivse as to what to look would be most appreciated.

The "ticking" sound is coming
The "ticking" sound is coming from your front atuolocking hubs! I had the same problem with the '91 Explorer I previously owned. The "shift-on-the-fly hubs are worthless...only shift into and out of 4x4 when stopped! There are several plastic components inside the hubs that will self destruct if the hubs are not fully disengaged. To fully disengage the hubs you must stop, shift out of 4x4 drive and place the vehicle in reverse and back up for at least 18-25 feet. Even then when you drive forward roll down the window and listen for a small grinding gear noise.
If your engine overheated
If your engine overheated because of your radiator problem then you may have droped a lifter.This is vary common.Lifters can sometimes be pumped up by cleaning them by adding a qt.of GM auto.trans oil to the crankcase and running it for a week or slowley pouring it down the itake TB untill the noise goes away.It will smoke like hell but this will stop after you stop pouring the oil.If this don't work you may need a valve train overhall.$$$$ AL
