1-2 shift chirp, Tire update, Polishing, & Diff. fluid
 

I have found out that with these skinny tires from the Tahoe, if I am turning and give it a little gas, the 1st-2nd shift will chirp. With a 305? What gives? :confused: It's really cool, but a 305? No muffler did give it horsepower! :burnout: :devil: Hehe...

Anyways, I did get my one tire that poped - ended up being $87. I still have the junk tires on (making me squeak everywhere and peel out when there is paint from a crosswalk)

I am polishing my rims, but only have 2 done. They took me 2 hours each doing a half ass job! Is there an easier way to do this? I'm using Nevr-Dull w/ the cotton or whatever it is that comes in a can. Works well, but takes forever and alot of it! I can't get the holes clean. Any suggestions?

I'm changing the differential fluid out this weekend. I don't think it ever has been changed, so It may have solidified a little (I've seen it before!) I'm a little afraid. I'm going to use 80W-90. The right stuff? I think the bottle I got was partially synthetic. Any positives & negatives associated with it?

you gotta run dino oil in the rear if you gots a positrac, i'm not sure about the stock ones, but on eatons and auburns you cant run synthetic

I have never heard that about synthetics with a posi. I am not disputing it, just never never heard it before. I have an eaton posi and I run Lakewood BFL fluid and it seems to work pretty good, although it is expensive. Most racers I talk to swear by it though.

I use Lakewood BFL with my Auburn. I'm not sure on the synthetic, but if you use regular oil, you need to use some additive with a posi.

I don't have a posi so I don't think that will be a problem. It is some "premium" Valvoline stuff. Only 80W-90 they had - they were out of the cheap stuff. Better for it I hope!

BTW: How much do the 10 bolts use? I bought 2 quarts. Will that be enough?

No, it takes about 2-2/3 quarts. Fill it until the oil starts to run out the fill hole.
