good question... everyone should have a manual for their vehicle, and the library should have a professional manual available...in the reference section, you'll have to make copies of the important sections...good luck :)
A 2WD Tahoe does not have torsion adjustment bolts, it uses front coil springs and not torsion bars.
Get under the truck safely and you will see a bolt head sticking down near the front of torsion bar on the adjuster; simply adjust both sides EQUALLY. If you jack it up too much, it makes the ride rough and is hard on ball joints. Make sure you get your front end aligned after you do anything with the torsion bars.
Weak torsion bars
Yes you can Adjust the torsion bar to raise it. I did this on my 1 ton Chevy to raise the front end. I had an alignment right after and it has worked great ever since.
NO......
Check universal joints if possible throw some grease on them and if it doesn't improve then most likely they have to be replaced.. Check universal joints
NO it is not. But you do need to change the oil and filter.
Do you hear a "ping" when shifting from Park to Drive or Reverse? Do you hear a "Squeak, squeak" going down the road Is there any play in "U" joints?
No you do not, it is not in the way. First remove the transfur case from the back of the transmission. Then you will have enough room to remove the trans.
Need to check u-joints first. Then look at the shock bushings, and make sure there not loose.
Start with changing the fuel filter.
A 2005 Chevy Tahoe will take a maximum of 5. 5 quarts of oil. As always, it is best to check the level on the dipstick when changing oil.
