Hello all,

 

I’ve looked high and low for options. I have a 2024 Silverado 1500 Crew cab, 4x4. It’s got the SU8 differential. AEV makes an SU7 skid plate, but nothing is offered anywhere for the GMCH SU8 9.5”. What are my options? Has anyone modified the AEV shield? I’m doing some overlanding this summer and I’m just trying to protect my investment.

I recently wondered the Exact same thing. I would love to have one. I wheel the poor truck hard, May just make one when its not all snow and ice here.

I went ahead and ordered the AEV plate. I’m going to do some modifying to the plate and the differential this weekend to get it to fit, and I’ll get back to you. Stay tuned.

So, I did some modifying. Used pipe straps to hang it and foam under the strapping and the plate to insulate it against rattle. It fits. No cutting or modifying necessary.

I like the skid plate, but I wouldn’t trust those straps to hold on if you actually hit the skid plate on anything. Did it come with any mounting brackets or hardware to attach it?

It did. Problem is, the brackets don’t fit the SU8 diff. It’s a different shape, but the dimensions are all the same. If the U-bolts were about an inch longer and the bracket was a different shape, it would fit perfectly.

 

I think I might take some time and double up on the straps to ensure a good, sturdy system.

I'm sure I'm in the minority, but I think it looks awful even if it had the proper brackets.  I'm thinking of function in a MN winter as well and all that would collect in it.  Not to mention anything that would damage the differential isn't going to protect it with that skid plate.

You haven't been off roading and hit a rock with that stock steel rear diff cover then. Seen several people who did and peeled it back enough to lose all the diff fluid. It's more to slide over stuff than protect from damage to the diff housing itself since it's cast iron. The big "ears" for bracing to the axle tubes are what will snag as well as the steel diff cover that hangs down below the diff housing. I ended up putting an AFE aluminum diff cover on which doesn't hang below the diff in the center.

I have to disagree, only because I have shattered a couple of differentials and wish I had installed a skid plate to protect them… I’m doing some over landing this summer on an expeditionary camping trip… And I’m just trying to protect my $50,000 investment. $400 for a skid plate is a lot better than $1500 plus for a new axle assembly. I really really don’t wanna have to go that far. I appreciate your opinion, but I don’t agree.

I may still do a differential cover, just for extra protective measures… The terrain I’m going over is really rough, I’m even going with shock skid plates. If I lose the plate while sliding over a rock, I have plenty of strapping to replace what came off… That’s why I’m not too terribly worried about it. I’m just trying to protect the differential as much as possible. Unfortunately, they don’t make brackets for the SU8, and I wish they had. I could probably modify these, but it would take quite a bit of time, and I’m not sure that I want to go through all that. I’d rather just use the plumbing strap, and double or triple up on it to make sure it stays on the truck.

      Oil pump noise was discussed before.  I will try to remember to record a remote start later this morning.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65

      Factory front brake rotors...defect?

      By Chris80s · Posted

      On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!
