#579 of 762 2002 Chevy Tahoe- Front wheel berings need to be packed.
Nov 23, 2009 (5:02 pm)
My left from wheel is making a sound like I have hug mudding tires on, my husband removed the left front tire in hopes to grease and pack the bering but discovered he couldn't get to them. If you know what type of berings these are please let use know do we need to replace the whole thing or is there a way to do it from home to save the money and not take to dealer. If you have done this job from home and can tell us how please let me know. Thank you and happy holidays.

if the bearing noise is that loud I'm afraid it's beyond the point of packing with grease. I mean, that might get you by for a little bit but the damage is done. Bad bearings can, in extreme cases, cause a lot of other problems as well.
Front Wheel Hub, Bearing, and Seal Replacement
Notice: Never place vehicle on the ground with the halfshaft removed or the halfshaft nut torqued improperly. Otherwise, bearing seals may become dislodged causing premature wear and/or damage to the hub and bearing assembly.
1. Raise and support the vehicle. Refer to Vehicle Lifting.
2. Remove the tire and wheel.
3. Remove the rotor.
4. Remove the wheel speed sensor and brake hose mounting bracket bolt from the steering knuckle.
5. Remove the wheel hub and bearing mounting bolts. (15 series)
6. Remove the wheel hub and bearing mounting bolts , the 25/35 series.
7. Remove the wheel hub and bearing and splash shield from the vehicle.
8. Remove the O-ring seal from the steering knuckle bore, the 25/35 series.
9. Remove the wheel speed sensor mounting bolt.
10. Clean and inspect the O-ring seal, the 25/35 series.
11. Replace the seal if the following conditions exist:
o Dry or brittle
o Compression set
1. Clean all corrosion or contaminates from the steering knuckle bore and the hub and bearing.
2. Lubricate the steering knuckle bore with wheel bearing grease or the equivalent.
3. Install the O-ring to the steering knuckle, 25/35 series. Notice: Refer to Fastener Notice in Service Precautions.
4. Install the wheel speed sensor mounting bolt. Tighten the bolt to 18 Nm (13 ft. lbs.).
5. Install the wheel hub and bearing and splash shield to the vehicle, 25/35 series.
6. Install the wheel hub and bearing (4) and splash shield to the 15-series steering knuckle.
7. Install the wheel hub and the 15-series bearing mounting bolts. Install the wheel hub and bearing mounting bolts, the 25/35 series. Tighten the bolts to 180 Nm (133 ft. lbs.).
8. Install the wheel speed sensor and brake hose mounting bracket bolt to the steering knuckle. Tighten the bolt to 12 Nm (106 inch lbs.).
9. Install the rotor.
10. Install the tire and wheel.
11. Lower the vehicle.

my 2002 runs rough, it bucks and wants to stall. The voltage gage bounce all over. check engin light say lean left bank lean right bank. it is almost lie it has a vacume leak. do you think it could be intake manifold?

Check fuel pressure. Could be a fuel pump going Tango Uniform.
#583 of 762 '96 Tahoe Tranny "zzzzzzz" noise
Dec 14, 2009 (10:24 pm)
I just spent about 4 hours reading all of the posts... this is a GREAT place to be!
Ok, bought my '96 Tahoe LT in April, with 150K miles on it, of which 10K are mine. It has a full tow package on it and I first made use of it with a 5x8 U-Haul trailer this past weekend. About half way into the 700 mile trip, I was entering the Trans-Canada from a ramp and, while accelerating, at about 45-50mph, there was a "zzzzzz" sound, kinda like a power steering pump, but from the tranny area. I was in OD, shifted to D, same noise with power on, it stopped when I released the gas, but no noise at all in 3rd. Everything still worked fine, passing gear, etc., no sign of slipping and the noise quit at hwy speeds.
When I stopped an hour later, for fuel, checked the oil levels, all ok, then put it through the gears. Noise in forward & reverse, with brakes on and slight gas pedal, but it did not last. I finished the trip with no further noise, and no drop in performance and no obvious slippage.
Without the trailer, and in our new snow, I've been putting it through the gears a little more aggressive, but everything seems ok.
I'm doing another 300 mile trip with aging Mom & Dad at Christmas and don't want any problems... any ideas??
Tranny oil is ok and, red, not burnt. Thanks

Get under the hood and pull apart, clean and "white-grease" all the electrical plugs and connections you can find... could be some wires giving mixed, (corroded, loose) signals.
A smoke-test, for the vacuum will show all leaks, 20$-40$, but worth the bother, even if that's not the "real" problem... could be a combination of things, vacuum is a good thing to have!
Might be a bad plug, injector, wire... battery connection= low, irregular voltage leading to computer confusion.
But the smoke test will tell a lot, and eliminate that question!
What conditions are you driving in?

When I do the scheduled maintenance to my TAHOE (oil change), what do I have to do o reset the "OIL LIFE %" message on the dash screen?? Do I have to make some kind of rest or does it recognize oil was changed???

#587 of 762 Purchase 1999 Tahoe?
Dec 20, 2009 (2:20 pm)
I have the chance to purchase a 99 tahoe for $750. It has 135000 miles and runs. The engine runs rough but when I put my hand over the exhaust pipe it isn't a miss in the firing. The car has sat for 2 years. it blows hot air, but when I checked the antifreeze it was half full. This is a corporate vehicle so it has been maintained. I did drive it and it drives with the roughness and gets up to 65 easily. I have read about many intake gaskets, fuel problems, etc. and wanted someone elses point of vew on the . the truck is in great shape and has all the bells and whistles. it is an 8 cylinder, 2 wheel drive LS. Thanks in advance for any comments.

Well you could have it scanned for trouble codes, and also do a cooling system pressure test to see where the coolant went---you'll have to find that leak regardless.
