How to measure gm rear end Videos

I have a skip/bang in my 93 z71 truck.. but it doesn't do it all the time, or even when taking off.. it acts like there is a tooth chipped in the rear end some place. Only does this when it is first starting out. Or a cold morning so to say. Also bumps cause this bang in the drive line to occur. Few months back I hit a stump hauling wood. The truck was vibrating really bad. Esp after I unloaded the wood. I thought it was stuck in 4wd. So I revved it an shattered the driveshaft into pieces. I got another drive shaft. Truck still vibrates really severe. Stops after about 70 mph tho lol. Yolk is worn out pretty bad where U joint attaches. Cup is bigger on the Yolk end. An it still has play. Loose. Replaced a bunch of em so far. Im expecting my first child in December an im really needing opinions of some one with more experience. I am a welder/mechanic so I can do some work on autos. Should I buy a rear end completely or do a # like in the video above ?? Cheapest fix is what im wanting. Doesn't bother me to take rear end off. Any advice is helpful. Thank you.

so if i have 4:10 i shouldnt drive it on the highway?

I have 2014 ram 1500 can i swap the limted slip with lockers ?

I have a 91 Silverado 454ss stock truck just have a four inch lower in the back ...also stock tires and rims, the differential starting to make this really loud noise ,so I went to check it out took the cap off found no fulid in there it was dry burned everything out ...so now I'm looking to rebuild it ...but I want to upgrade the gears to 4.10s. with posi would that be ok to drive around the streets and freeways?? not a everyday driver

I have an lt1 5.7 in my 1991 S10 with a th350 and 3:08 gears on 235/60/16 tires. I was trying to get more acceleration but I don't want to use it for strictly drag racing. I want it to be a daily driver that I can play around in when I want, without it drinking too much gas. What gear ratio do you think I should go with?

I had a quick question.. I have a 2011 chevy silverado 1500. 4.8 with 3.23 gears.. I recently motor swapped it to a 6.0 with Longtube pacesetter headers. With a 226/230 Comp cam. Black hawk c.a.i. K&n 3200 stall. Tune. Take off power is there But top end feels a little sluggish... Was wondering if 3:73 would help me out.?. 

I have an 88 S-10. I just pulled an 5.3l from a local junkyard with 89,000 on it. I ordered a Z06 cam for it since I plan to boost it later on down the road. I'm saving up now to get the Currie Ford 9" rear you carry that is a direct bolt in. I have no idea where to go gear wise as this is my first attempt at building a vehicle. I know I'm going in the street/strip area, but I do plan on driving it on good days as well a little track time too. Any suggestions in a gear selection please?

i have a 1991 trans am LB9 305 TPI 700R4 with a G80 2:93:1 gear i was thinking of 4:10: or 3:73:1 the car is only drove local it does not go on road trips very far maybe 30 miles at best i have a cold air intake flowmaster exhaust shorty headers and y pipe 2.5" and 3" pipe back to the muffler i also have underdrive pulleys and 1.5 full roller rockers and a 180 deg thermostat and a stage 2 jet performance chip which gear do you think.

i sure hope you find one you should make a video and tell the guys to start looking around for you too.I have a 12 bolt posi in my 68 chevelle and it has 488 gears in it i cant wait until you find one i will be looking for you.send me your tel# in a msg i might have some leads on a 69 later

how would you calculate for a 3.73 ?

Are we sure its 2 revolutions? I swear its only 1...could be mistaken tho
