Noises in the back of your truck?

Check your spare. I got under my truck the other day to check the tire pressure in my spare. When I pushed up on it, it made noise against the frame.

 

My truck was purchased in September 2013, so that spare has been sitting under there for 10 months, undisturbed. Or so I thought.

 

When they install that spare, and winch it up into it's resting place, I'm sure they must turn it up until it reaches a set torque reading. The spring obviously compresses as the cable is winched up. I would assume that the cable over time, being brand new, probably stretches a bit, and the spring probably compresses a bit, with the weight of the rim and tire pulling on it at every bump, crack, or pothole in the road.

 

I took out my tire tools/jack handle sections and completely lowered my tire to the ground to check the cable, winch operation and function. All was well, and it operated as designed without any hiccups. When I seated the tire back up against the frame, I torqued it down pretty good, compressing all but he last coil or two of the spring. Thinking about putting some closed cell foam between the tire and the frame, to take up some of the compression, and act as a buffer/sound deadener.

 

Get under your trucks and give your spare a good push up, you might find this is where some of your noise is coming from? Your cable and spring has probably relaxed a bit, as mine did over time? I do know mine was good and solid when it was new, because I checked it. People that didn't have any noises when their truck was new, but do now, might want to check it out?

Thanks for the update. I'll check if mine is loose sometime today. I don't have any noises but could be a source of vibration for others if its Loose banging around at speed?

I had this same issue. Had noises coming from the rear. Took 3 trips to the dealer before they fixed it. They started with replacing both of my shocks. next trip they checked spare tire to make sure it was mounted properly and lubricated coils. the third trip they replaced both rear leaf springs and that did the trick. I haven't had a noise since.

a buddy told me to drop the spare and grease the cable so it doesn't rust out. makes sense... ill be doing that in a couple days.

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

      By asilverblazer · Posted

      Yes.   Yes.   We might be intermingling ideas with the term 'severity', in one of my past vehicles it could pull up DTC via the vehicles own user interface, at any given time when one would do this there would be an assortment of codes that were 'trivial' including 'communication' issues. This would generate a bunch of, potentially false alerts or some many that they would get ignored. Which you mentioned earlier.    You also mention several things that might be redundant with the vehicles own systems or indicators: The truck has an oil pressure gauge, monitoring it via this other system wouldn't be a priority except in comparison to other values or if there is an actual oil pressure problem.   Same thing for miss-fires or other problems, the MIL already signals the operator to an issue...   ...to the point about what one wants to see first, if there is a miss fire detected, I want to see miss fire counts or fuel trims first, if I have an oil pressure problem I want to see the oil pressure first. So, perhaps the 'systems' that are showing abnormalities are what gets displayed first.   I think your device is what connects at the OBD port, ease of use for the consumer, it could still have a 'pass-through' port for a second scanner, computer, etc.   Yes.   Based on my comment above, if an error appears, the report would be more specific to the system having an error.

      I like the idea.  I thought about putting a deposit a few years ago when they first dropped.  I still want to drive one and have inquired about doing this with them, like a ride and drive event they said they are coming but it hasnt happened even with them built in Indiana.

      Transmission Woes :-(

      By asilverblazer · Posted

      That's a tough spot to be in, I personally would question spending 1/2 the book value on a repair vs. selling it as-is.    Presuming you own it out right, sell it for 10k and have a down payment for a replacement truck, or spend 10k on the one you already have...   I still think there is a cheaper transmission out there via recyclers, aftermarket or rebuild. (Cheaper than 5k for the unit)

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Sadly, there's a drought of good 92-95 4.3 cars at junkyards in the area otherwise I would have gone fishing for parts. Not that they don't come up, there's just nothing good in the yards right now.   I tore into the intake yesterday evening, easier than I thought, and I might have this problem licked for cheap. Two of the intake studs came up with the bolt on removal, no big deal but that's why it looks funny with studs only on one side.   There's pooled gas on both sides of the plenum. Highlights boxed in green. Picture-right side has an obviously split pressure line from rubbing on the #5 injector nylon line. #5's line is worn in that spot but not all the way through. Passenger side intake (picture left), not sure, but I think the pressure regulator is hosed. Rebuilt spiders don't come with the pressure and return hoses so I'll need to replace those no matter what. A pressure regulator is $30 so I'll try that and if I end up having to swap the whole spider, it was $30. I'll be grinning ear to ear if that's all I need.   Parts arrive Tuesday.   Sure enough the shop was here before. That's a new gasket. Vacuum lines and wiring are a tangled mess, I sorted that out last night as well. Spent about an hour just picking up general slack and shoddy reassembly around the engine bay. Cheek-pokered the battery tray, got it all cleaned up. Sometimes things just need a little elbow grease and a few minutes of time to be right again.
