I can tell you that from having already bought a set of rotors for my own
'91 Ranger XLT, those Autozone rotors are way overpriced. I think I paid
around $45 -$50 each for mine @ Napa. ANY parts I have bought for my truck
have not been expensive, it is very cheap to maintain. As for the whining
you are talking about, I've had my truck 4 years and it has always had a
noticeable whine from 1st to 3rd gear, 4th and OD you can barely notice it.
Note that my truck is only 2wd, so yes, the noise could also be something in
the 4wd driveline. Anyway, I'm not sure if your truck has the same Mazda
transmission that mine does, but it is more than likely making the noise you
are talking about. BTW, my transmission was rebuilt 3 years ago and it had
no effect on the whining, it still does it now. I just learned to turn the
radio up louder. My truck has just over 245,000 kms on it.
FYI, www.therangerstation.com is a great resource on the web for these
trucks. I will also tell you about the only two major annoyances/problems
I've had with this truck. The first is the rubber plugs on the top of the
transmission, if it is a Mazda unit and the plugs have not been taken out
and replaced with steel or equivalent. This should be one of the first
things to check/fix. Those plugs are known to leak and after time your
transmission will lose fluid. If it gets too low like mine did, you WILL
damage the transmission. It overheated and broke the tailshaft in mine.
The site I mentioned above has a great article to explain how to fix the
The second thing are both the EEC and fuel pump relays are known to stick
and cause electrical problems. If it ever happens, you'll think that either
your battery or alternator has just died, after your truck refuses to start.
I went through a year of replacing new batteries, testing alternators and
checking wiring before I finally found an article on the internet explaining
the problem with these relays. The fix? The two relays are the same, buy
two of them, replace them. It is a 2 minute job and it is well worth the
time and money for the relays, otherwise you will drive yourself crazy
trying to figure out whats wrong with your electrical system.
Otherwise, my truck has been great to me, now I just need to get some body
work done and a new paint job on it.
Good luck if you decide to purchase.
