is it ok to go from 235 70 r15 tires to 235 75 r15 on a 1999 gmc jimmy
Yes its ok, the 75 tires are a little taller. your speedometer will not read correct speed, you will actually be going faster than what it reads.

what is the check gauges light
CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.
If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

Before the reverse went out it always acted a little funny(in reverse). It would kinda shudder when gas was applied during reverse and then one day reverse was gone. Please help!

We have had our Jimmy into a local repair place twice for the same problem. Today it happened again for the third time. The engine begins to run hot and the coolant reservoir is found to be empty.
The first time they replaced the thermostat and water pump. Refilled the coolant system with proper mix of antifreeze. Within one week of being home the Jimmy did the same thing overheating and the reservoir was found to be empty again. Second repair trip they replaced the radiator, fan clutch, and the thermostat for a second time. Within three days of short drives (less than 5 miles each day) the Jimmy started overheating and the reservoir was found empty again.
I guess the burning question is , where is the coolant going.
Is this a 4.3 engine? How many miles does the vehicle have?
Has the intake gasket been changed?
I'm guessing a can of "Bars Leak" may cure your problem.
Let me know.
Regards,

I just bought this truck about 2 months ago. Just recently the SES
light came on. Had it read. Turns out to be a P1345 code. I have
replaced both the cam and crank sensors. Since then when first
accelerating at very low rpm's I can feel the misfire. Or at high
speeds(70-75) around 2000rpms the same misfire happens. I got off the
highway when this happened. Had the truck scanned again. Same code
P1345 and a misfire code. I have recently(past 2weeks) changed the
plugs wires cap and rotor(same time as the cam sensor).
With the recent plugs wires cap rotor and cam sensor the truck ran fine
for a couple of days then the P1345 came back. The truck ran fine. Had
the scan tool hooked up and it cycled and no misfires. About 4 days
later the light came back on again(each time it was cleared). Scanned
again and it was not cycling. Changed the crank sensor. Now cycled a
random misfire after the truck had been running about 20min, but then
the computer cleared the misfire(no code thrown). Drove the truck
around and about 3 hours later when I started the truck the SES came
back on. Drove it around and could feel it misfiring again but only at
low speeds(didnt want to push it on the highway).
I need help because this is starting to **** me off.
I did read online that when I replaced the cap rotor and cam sensor
that the distributor possibly might be off a bit and could cause this.
I did get all of the repair reciepts when I bought the truck and one of them was the distributor was replaced through a recall.
Any help?
Well that sounds like a tough one , But here is a site worth checking out . Several mechanics use this it to help out people like your self that are frustrated and are getting P #$%$# off ! Good luck

How to change my front differential seal and bearing ? passenger side.
I bought a new wheel bearing because of a humming sound on passenger side and doing so saw leaking seal and maybe the humming was commng from differential inside bearing ?
That will be a Huge job. The whole front diff must come out of the car and the case will need to be taken apart to even gain acess to the carrier side bearings.
The hub bearing is where the wheel bolts up is that maybe what you are talking about?
Also the axle seal isn't that bad to do you need to remove the cv shaft then it's just a simple remove the seal and install the new one.
But all of these jobs will be big ones.

GMC jimmy key stuck in ignition, steering column will not lock, electrical system working
It sound like your shifter linkage is worn and your ignition interlock is not making it into the park position. I'm not 100% sure on jimmies but my GMC Sierra could be adjusted on the steering column under the hood. It's just a rod through an eye with a bolt. Put the transmssion in park and loosen the bolt and twist the column until the indicator is in park, retighten the bolt.
