Replying to: jeardm (Dec 21, 2008 6:55 am) Changing gears are often overlooked and offer an economic solution to acceleration. With 33's have you considered 4.56?

Replying to: jeardm (Dec 21, 2008 6:55 am) I have an excel spread sheet that gives engine RPM for different size tires/different rear axle ratios/and final drive transmission ratios. All you do is enter in the information and it calculates the engine RPM. I am new to this forum so I don't know how to get it to you without an e-mail.   Terry Replies to this message: jeardm (Dec 23, 2008 6:56 pm)

#33 of 38 After Market Diffential by 2000GmcSierra Feb 17, 2009 (7:42 pm)
I have a 2000 Gmc Sierra 4.8 and I want to get a posi-unit. maybe a eaton with 373 gears. but i really dont know alot about them besides that both wheel spin and the truck gets a good take off with good traction. Could anyone give me advice on what to look for when buying one and what would be a good price to have on installed. I asked a shop and they gave me the price of $1100 Installed. its an Eaton Differential, bearings, and 373 gears and the instalation. I live in Southwest Detroit, Michigan where here chevy trucks are popular and gettin them down to 11's is everyones goal. my truck is stock and it just has a k&n. my email is Juanelo_Irreziztible2008yahoo.com if any wants to write me on there. thanks

#35 of 38 2001 Silverado 2wd Rear Differential by hunterg10166 Feb 22, 2009 (1:51 pm)
I have noticed latley that my rear diff will "lock" up when making turns and it sounds and feels like I am draggin the outside rear tire. This mainly happens after a fast start. I just changed the diff fluid 2 weeks ago nad inspected the oild fluid and didnt find any shavings. This is an itermittent problem. Any ideas? It is the G80 rear end too.   Thanks, Scott

How do you replace a center support bearing ? 1998 G.M.C Sierra 1500 2 wheel drive. 5.0 V-8. Replies to this message: akjbmw (Mar 09, 2009 12:04 am)

Replying to: aserednyj (Mar 07, 2009 10:43 am) Short answer abridged from Second Edition Service Manual for '98 Chev/GMC... It appears that the center support bearing is a press off/press on arrangement. You do not want to use a hammer.   Support everything to prevent excessive bending of joints. Make reference marks to put things back in the same orientation for balance. Start by removing the rear u-joint from the differential and tape the joint to keep the caps from falling off and loosing the needle bearings. Next remove the center support bearing bolts and remove the assembly. Install in reverse order. KEEP EVERYTHING CLEAN and re-clean before assembly. A longer answer involves knowing if it is a two piece or three piece assembly, if it is a Dana or American Axle propeller shaft, and how much it will cost to have it towed to a repair shop if you loose something.   The last center support bearing I replaced was on a '70 BMW 2002. I've slept a few times since then. No pressing. Just a stubborn circlip and rubber flex joints that required compression to align bolts on re-assembly.   Good luck.
