I need opinions on 4 issues: (97 Chev 1500 4.6L 5speed)
- TIRES -235/75/15 - My spare is a brandnew uniroyal Tiger-paw. I need 4 new tires. I was going to get 3 matching tires to my spare to save $$$ because that is an issue. However I have been told that Tigerpaw tires are garbage. I need more opinions please on what to do.
- O2 SENSORS - The truck is starting to miss a bit and am assuming it is the O2 sensors. I don't know if they have ever been changed (151000kms/94000mi) Apparantly there is 4. Should I just change all 4? or is there a way to test them to see if they work?
- A/C BELT - The truck has a/c but I was thinking of (to increase power/save the bearing/ increase fuel economy) to put a different belt on that is designed for trucks w/o a/c. Is this a good idea? Will it work?
- GEARBOX - It seems when the truck is in neutral with clutch in, when i release the clutch there is a whirring sound, very faint that sounds like a bushing or bearing is starting to go. Can someone confirm this please?
'luckystrike' sent me this, is this what he is referencing?
" The input shaft on the tranny just sticks into this bronze bushing. As it wears, the input shaft vibrates, and causes undue wear on the input shaft bearing. If you change the pilot bearing, put it back together, and it still chatters, your input shaft bearing is worn. "
Thank-you in advance!
