I did something real bone-headed today and now I want to find out what my rear gawr is with the towing package (not sure if I can trust the door plate since the package was an add-on). It's a 1997 k1500 4x4 with towing package, crew cab, short bed.

 

The plate says 3700 for the rear, but here's the thing: I had HomeDepot put a whole pallet of shingles on the back (about 3300 lbs) before I thought about checking the gawr. Yeah, that was stupid, but I never have really hauled anything heavy before and just didn't think. The rear sunk down but I made it home (about 4 miles) without any bangs or other problems, and I checked the springs after I got home and no obvious problems, so either I was real lucky or the actual rating is higher, cuz I KNOW the back of the truck doesn't weigh less than 400 lbs.

 

Anyone know specifically for this truck? No doubt if I have to do it again, I'll make sure I don't overload, but just curious now.

what's the gvw? I would go by that before  axle rating, weigh the truck empty and subtract that from the gvw and thats your payload.

I'd bet it's less than 1,900 lbs.

 

Never seen a 4 door crew cab that old either unless it was a 2500/3500. They were all extended cabs in the 1500;s.

payload on my 98 k2500 is around 2400lbs . weighs 6250 empty with full fuel tank, gvw 8600.  it has a liftgate on it that's around 500lbs and plow gear so bare bones it would be close to 3000. that's pretty good for a 3/4 ton truck I think. it gets overloaded quite frequently and handles it well, doesn't bottom out even at 1000lbs over gross but I did notice a rear axle seal leaking last check over so I'm thinking the axle may be worn where it rides on the bearing. I just bought another truck so I can take the old girl out of service for some TLC. that's 1 thing that a full float rear diff has over semi floater. no axle wear

I would be more concerned with the load rating of the tires than axle rating, lots of light duty trucks have passenger car rated tires on them. If the first letter in the tire size is P thats a passenger car tire even though its the correct size it's really not engineered to carry a heavy load

      I love my truck but

      Those  headrest speakers look fun! Standard panoramic roof on the AT4X might be a deal breaker for me unless I can delete it. Maybe I should just supercharge my truck and call it a day. We'll see what I think of all the new trucks when I see them in person.

      "Increase"?   You want to "increase" your turning radius?     What is your truck?  What kind of cab and bed do you have currently?  Is it stock?  Modified?  Lifted?

      Transmission Woes :-(

      OP's quote is parts and labor.  Not just parts.     The # you found isn't the right one.  But besides that, the right # is the same price within a couple bucks.  $5802.01.    Now, factor in labor and fluids.  Book time is 17.1 hours for a Colorado 8 speed.  At $200/hr for a dealer average rate, its $3420 just in labor.  We are already at $9222.  Fluid and other necessary items, there's your $400-500 more.      Also.  Your "discounted" transmission.  Which is 99% likely quoted off of GM Parts Direct as that's the MSRP I found on their site.    You failed to note the $597 in shipping charges.  So we are right back almost to MSRP.  $5794.  Oh.  AND, you better have the $4000 for the core charge which you'd have to pay and get refunded, AND you gotta pay to SHIP THE CORE BACK.    So now you'd have paid MORE to buy that one online yourself, even after you get your core refunded.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.
