I have a 06 GMC 2500HD. What is right length of wiper blades. I have 22" now and drivers side hits window trim on left side windshield but does go back to bottom of windshield. Is there a adjustment on swipe of blades

or are these too long ? It drives me nuts. The right side works fine. Thanks for any help.

22" is the right size. You can adjust the angle of the wiper arm on the stud and see if that helps any.

 

 

 

 

How do you do this? Thanks

At the base of the wiper arm is a black plastic cap, remove, then losen the bolt, the arm will be free to reposition, note this arm and post has no grooves or ridges, just a tight fit made to slip if it jams( vs striping like the older model types had), then rettighten ...

 

snow & ice can make them slip a litle so readjustment may be needed every so often ...

I disagree with the quote of cosmic Charlie above .

 

Yes remove the 13 mm nut , wiggle the arm off of the wiper transmission post ,

Always do this in the park position ( off)

 

Lay the wiper arm on the post and level with the bottom of the windshield , never adjust it at the A pillar ,

 

There is nothing wrong with putting on a smaller blade , it'll be a 1/2" difference at each end for a 21" blade ,

 

And wiper arms don't need to adjusted periodically, hogwash imo of course

Never had my wiper arms slip. Only time I've ever had to mess with it was if I didn't line the arm up well after replacing the wipe linkage.

I don't believe that either. Not sure about these newer trucks, but my 98 it's just a gear at the end where you slide the arm onto so it won't slip and it had a notch so you can only put it on in one position. That was also easy as hell to take off, just a clip that you slide up and then the arm just comes right off. I'm pretty sure the newer trucks have it similar or some other way to make it not get out of alignment.

Ya those older trucks where idiot proof , newer ones have no "key" just splines

I knew they came off easy, but I didn't see the notch to line it up with until I thought the driver side was higher than the passenger side when down so I was going to rotate it. I guess it was supposed to be like that, never bothered me just figure I give it a shot and then find out it was only one way it could slide on.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.

      Missing thrust bearing? And oil selection

      There's absolutely a mountain of profit in catering to the "I do my own research" crowd, people who are certain they know better. And I don't mean there isn't data to support that 0w40 produces less wear product than 0w20 in an engine like the 3.0 Duramax, that only feeds them the assurance they need. Again, my whole thing with oil selection is, sure, 0w40 or 0w30 produces less wear product. Are we talking the difference between the engine lasting only 100k versus 200k? Or are we talking more like, if the engine will already go 350k on a good 0w20 regimen recommended by the OE, is using 0w40 going to get us to 355k, assuming we can even get the rest of the truck to last that long, meanwhile sacrificing the first 5y, 100k in powertrain warranty. The answer isn't easy, there are tradeoffs.   I willfully use 0w20 Dexos D for this reason, knowing that a 0w40 will produce slightly less wear. I don't believe the delta in wear product is meaningful over the lifetime of the engine, and I place much more importance on driving style and overall feeding and care of the engine as a whole. It's the mentality that someone can abstain from alcohol their whole life which is an amazing boost to health by itself, theoretically. But if they're sedentary, that lifestyle choice will most likely kill them young despite their other, concerted efforts. Maybe someone doesn't drink AND they are the perfect picture of health and activity AND they use 0w40 AND they treat their engine perfectly. If living until 130 years is the goal, sure, do that. But it's going to be a really old truck falling apart around a good engine for that last 30 years, without a doubt.   I watched Demonworks' other video on the 100k+ 3.0 Duramax that had dealer 0w20 changes on what appears to be OLM-prescribed intervals (8-10k).   The QR codes are still present and readable on the main bearings. That's how little wear it has.   That's not proof that anyone else should stick to 0w20, but it's confirmation, for me, that 0w20 is perfectly acceptable to use in these engines.

      summer road trips in the 2026 2500HD

      oh ya that's good to know - I would rather use a gear than the brakes down a long hill.  I would not let cruise control take over on snow or towing a trailer for sure on hills anyway.     The other thing about the CO trip was that was all done above 6K feet for the most part, so that has to use more gas as the motor is down a good amount of power up there.   If I drove my 2016 Camaro with a very similar V8 to this 6.6 it would probably get about 23-24 on the fast run up to NE.  But the premium fuel premium is steep here in CO, so it would still only save about $40 in overall costs for the round-trip.  And you sure can't carry much gear in a convertible camaro!
