    RPO Codes for Rear End Gearing

    I have looked around the site but can't seem to find the RPO codes to determine gearing in my truck. I have a 94 GMC K1500 ECSB 6 lug with the 5.7 did those come with more than one gear ratio? It has a limited slip rear end but not sure if it's a 3.73, seems those are the most common in these...

    Truck axle interchange

    I am in the same boat. What about all the specialized tools to get it setup are the tolerance that precise? I can find a low mileage rear end for about $250 so thats what I am trying to figure out chance it with a used or rebuild and chance it that I get the measurement right LOL

    Noise from the rear of my GMT-400 ECSB 4X4

    Update... Pulled the cover off and found pieces of teeth missing from the ring gear and a loose pinion/yoke. So now the question is which is the best for a driveway mechanic. I see the parts for rebuilding the rear end are not super expensive but setting it up seems to take specialized tools to...

    Noise from the rear of my GMT-400 ECSB 4X4

    I have been hearing a noise from the rear of my truck for about a month. Sometimes it was not there but within the last week it was louder and i could feel a knocking in my left foot when i had it flat on the floorboard. I jacked it up off the wheels and wiggled the driveshaft and the rear...

    My 1994 GMC ECSB Rebuild Slow and Steady

    Yea I am not replacing the whole rocker just the exterior metal about 18 inches worth. I added the panel in the indented area because it was easier to hide my substandard bodywork skills. I did not have to use much filler actually. And yes I ordered new brake and fuel lines already and will be...

    My 1994 GMC ECSB Rebuild Slow and Steady

    Well the cab corners are installed and primered... I will probably start stripping down the molding and working on the doors. I may have to replace the drivers side door, it has some rust in the bottom and is not in the greatest shape. Also plan on working on rockers.

    My 1994 GMC ECSB Rebuild Slow and Steady

    Yea I know... I am hoping I may be able to get to a 305 possibly if I have the right Offset . I like the added height but did not want to spend the money on a suspension lift.

    My 1994 GMC ECSB Rebuild Slow and Steady

    Well ... making more progress put the paint on today on the rear of the frame. Now to decide the next step. I am thinking I should remove the front fenders and hood next so I can get to the front of the frame to prep and paint it and the inner fenders. I am thinking that will make it easier to...

    My 1994 GMC ECSB Rebuild Slow and Steady

    Well I have the old shocks and spare tire wench removed. It occurred to me that shouldn't all fasteners be stainless steel. The bolts holding on the shocks at the top were so corroded and rusted it took several squirts of PB blaster to free them up. I started using the wire wheel attachment on...

    My 1994 GMC ECSB Rebuild Slow and Steady

    Well I pulled the bumper off today only had to cut two bolts on the receiver hitch :-) But I am having problems getting two of the bolts out of the receiver hitch... It needs to come off to get cleaned up and it will make it easier to re-install the bed when I put on the 3" body lift. Vacuumed...

    My 1994 GMC ECSB Rebuild Slow and Steady

    Well I have started the heavy lifting. There are 8 bolts that hold the bed on and after 19 years they were more than doing their job. It took about 10 hours to get them off even with PB Blaster and a torch, but they are off. I used a portable hoist to remove the bed and I will start getting the...

    My 1994 GMC ECSB Rebuild Slow and Steady

    Well I joined the forum a couple weeks ago and have been reading threads like crazy. There are tons of great looking OBS trucks in here and the more I look the more I get confused on which route to take. I am creating a laundry list of repairs starting with the body rust. It has the standard cab...
