2000 blazer Multi part question
ok, hate to be the new guy that asks to many questions but here goes.
1. my oil pressure gage fluctuates between 43, and 20. depending on rpm, higher=higher. well maintianed and plenty of oil. is this normal?
2. I hear a clunking when my auto trans shifts from 2nd to 3rd. sounds like it could be the u-joints and there is a vibration as well. wadda you think and how hard is the fix. and is the rear end oil easy to change?
3. Yesterday i had a rear caliper frezze up in the "Brake on" position. smoked my brakepad good. and also i had no brakes going home. i took it apart today and used a c-clamp to work the piston. it moved freely and i reset the computer and everthing works fine. i have the abs light on due to a severed abs sensor wire off of the driverside front wheelbearing assembly. what could have been the cause? i should mention i deliver pizza and i "chalked em up" a couple of times in the rain. Almost missed my street.
4. is there any good leveling kits out there? personal experinces?
2000 4x4 LS 106k used to tow 3 quads.
thanks guys i know im in the right place for info. Just look at this forum! BAD ***

RE: 2000 blazer Multi part question
In my experience that oil pressure is fairly normal assuming a fully warmed up motor and running 5W30 or 10W30 on a hot day especially if you're towing those quads.
A bad U-joint will make a clunk and vibration but doing it on transmission shifts is kind of odd. Usually I'd really notice it shifting between forward and reverse with foot on brake holding the vehicle still.
Rear end oil is not difficult to change, some of the bolts will be awkward to get at behind the rear sway bar but remove them and the cover, wipe the junk out of the bottom of the differential, and the fill plug on the side can be removed with a ratchet and extension. Take a screwdriver and scrape out that square hole first so you get a good bite. 2 quarts of gear oil will fill it.
Severed front ABS wires (from what I've seen) are caused by either someone replacing the upper ball joint and not reattaching the bracket on the wire to it or they unhooked the brake line and ABS wire from the upper A-frame when doing brakes and didn't put them back correctly (and it is awkward to get at that bolt)

RE: 2000 blazer Multi part question
yea just checked fluid, full and clean. just had it serviced when i bought it about 9 months ago. it definitly is clunking from first to second and second to third. once in overdrive just your nomal vibrations and shimmys. I had the u-joints replaced with hi end "napa" offroad ones. the mechanic thinks its my trany, and my transfercase has some issues too. he said it was making some noise when he cranked the front wheels forward and backward. Not real shure what he ment by that..LOL but i belive its in the trany, talked to my trans guy and he said it could cost up to 2k to get it lined out.
but mainly it does it beween 2-3rd. what is a sun gear? and how hard are those to fix. kina sounds like a berring that has slop in it. and if is that, how do i have till destruction!?
thanks guys

RE: 2000 blazer Multi part question
To replace the sun gear imagine your tranny disassembled all around your garage. Not a casual job. Incidentally your transfer case isn't fed fluid from your transmission, it contains its own special fluid (blue) available from GM (do NOT use regular ATF or gear oil). There's 2 plugs on the back of it, lower one is drain, higher one is fill (stick your finger in it to see if you get any fluid on your finger tip) If it was low on fluid it might've caused things to wear in transfer case. Might be too late to try changing it, but......

RE: 2000 blazer Multi part question
uh, lets see here. the story goes somthing like this. got the blazer about 6months ago and paid around 8k for it with 90k for miles. now i need to put atleast 2k in the drivetrain. hmmmmm, i think im gonna trade this damn thing in. now my question to you is what would be a good truck to haul my three quads? i prefer a truck but all i can afford is one with high miles, does the s-10s all have the same problem? and if so how about the full size Z-71? Ford f-150? dodge?

RE: 2000 blazer Multi part question
If your sun shell was going out, you would now it. There is now inbetween. If it goes out, you lose reverse, 2nd and 4th. No exceptions. Search for a tranny rebuild thread. I rebuilt mine at the beginning of the year. The thread is full of pics and info about how to replace the sun shell, amongst other things.
Your clunk is no doubt a u-joint. Hellofa lot cheaper then a new tranny.
Calipers lock up due to corrosion ont he slide pins or a colapsed brake line.
I am going to be blunt.
Unless your made of money and have a mechanic on staff, you should seriously consider changing your driving habits...

RE: 2000 blazer Multi part question
Oil pressure should deffinatly fluctuate, my blazer does and all of the chevy's that my pops owned did also. As you build RPM's it should build pressure.

2) Clunk is typically ujoints. Vibration could be a driveshaft out of balance, or most likely tires out of balance. Vibration is not normal. Get it fixed before you eat more parts.
