rear end problems
Well, it started yesterday. Popping when putting it into gear or taking off. I figured the trans had finally kicked the bucket(160,000 miles on the truck) Today, I crawled under there and checked all the u joints, they were still tight. I noticed that my carrier bearing mount was cracked so I welded it up. While I was under there, I got someone to hold the brake and put it in gear, the shaft is turning about 1/2-1" and clunking hard. Seems like there is excess slack in the gears. Now here comes the question. How much borrowed time am I on, it doesnt make noise driving, only on some take offs and putting it into gear. I need the truck to make it until next week when I have time to get to it. I have the gears already, but what installation kit do I need. I see some for $100 and I see some $22-35 dollars. I am keeping the open diff for now, going from 3.42s to 3.73s. I need to keep the price as low as possible until after Christmas, I have already spent way to much money this month. Also, these symptoms dont sound like trans related do they? I know the fluid still looks good, the temps are still normal, appears to be rear end to me.
Cliff notes:
How long will the clunking gears hold up.
what rear axle, spline count do I have(04 silverado open diff)
which one of these kits do I need:

I would think it's your spider gears causing the movement. I got a open diff with 50k on it I'll give you. I bought a bearing kit from bumper to bumper autoparts 75 bucks I think.

Thanks guys. So even if I swap out the ring and pinion, I could still have this problem because of the spiders. You know I forgot all about those being in there. I wonder if it was caused from those donuts I was doing the other day, or just general wear. I have done a ton of burnouts, but most of them were straight line. I think its just the mileage on them, both wheels have been locking up and spinning together now for months even though its open diff.
