    Leaking windshield fluid reservoir

    Nice, thanks for this vid! I actually did find the pump seal on RockAuto, it’s out of stock, but has a part number (Dorman 49520), so perhaps I’ll try this first before tearing out to the battery and replacing the tank.

    Leaking windshield fluid reservoir

    Ah okay, right. Thanks. Makes sense. Might as well replace the tank while in there if doing just the grommet anyway.

    Leaking windshield fluid reservoir

    Realized the windshield fluid reservoir is leaking on my 2004 1500. I marked where it’s dripping from. Looks like the connection to the tank. Can I get away with just replacing the grommet?

    Big brake retrofit for 2500 trucks?

    I’m thinking that since the 2020+ 2500HD trucks are heavier, even the dual piston brakes gotta be designed with better stopping power. I’m thinking of just biting the bullet and seeing if they will fit… Maybe I just need some spacers for the mounting bolts.

    Big brake retrofit for 2500 trucks?

    If you’re referring to the 1500 trucks, then yes. However, most NBS (00-06) 1500 trucks came with dual piston rears, which are arguably better than the subsequent calipers, so a refresh on the rears is all you need anyway. Keep in mind you’ll need 20”+ rims in order to fit over the big...

    Big brake retrofit for 2500 trucks?

    Interesting. Ya aftermarket is cool, but I prefer oem retrofit. What lug nut change took place in 2011?

    Big brake retrofit for 2500 trucks?

    As I’m sure you’re all aware of the big brake swap possible to simply bolt on the larger rotors and 4 piston calipers from 2019-2021 Silverado onto 1999-2014 1500 trucks… But, I’m wondering if a similar upgrade exists for the 2500 trucks? I believe the 2019+ Silverado/Sierra 2500 trucks also...

    2” rear lift but keep magneride

    You can keep the Magneride (it would actually be cheaper too), it just takes a little extra work to get the brackets to extend the height adjustment rod and wiring. Either way, depending on how high you go, you might need longer sway bar links as well. Bilstein are nice, but they are a...

    2” rear lift but keep magneride

    Ah okay, ya you’d just want to assure that the amount of lift (from the spring spacers in the rear and torision keys cranked in front) matches the amount extension by the shock extenders. So, the only difficult part (if you want to retain magneride) will be to manage the magneride height...

    Powerstop K6560-36 vs Detroit Axle Drilled/Slotted Brake Kits

    Btw I’ve not tried the Severe-Duty AC Delco, though, which I imagine could be a formidable contender.

    Powerstop K6560-36 vs Detroit Axle Drilled/Slotted Brake Kits

    I got the PowerStop drilled/slotted rotors, along with the PowerStop Extreme Severe-Duty Truck & Tow brake pads… and this combo is by far the best brakes I’ve ever had on any truck in my entire life. I’ve tried Detroit Axle, EBC (Green Stuff and Yellow Stuff)… none come close. I’ve put almost...

    2” rear lift but keep magneride

    Can you post the shock extenders you are talking about? I believe you’ll also need to get a longer rod for the height sensor.

    Question about center bore sizes

    I haven’t measured the center bore of these rims yet, but will do so when I take them off to install the spacers I ordered (which is what sent me down this rabbit hole to begin with). I’ll measure my center bore of the hub too. I would prefer everything sits extra tight, especially if adding...

    Question about center bore sizes

    Hey btw, just spoke to Lenny from Motorsport-tech.com (they make Bora spacers for 30yrs and measure everything precisely). He said that although the specs all over the Internet do say 78.1 or 78.3, if you use a micrometer to measure the actual GM hubs… They are exactly 77.8! o_O Apparently most...

    Question about center bore sizes

    Indeed, I see many sources specify either 78.1 or 78.3 center bore size for the NBS 1500 trucks… but, nobody else lists it as 77.8 I’m rather surprised at the level of discrepancy here, usually center bore size specs for wheels seem universally accurate.

    Question about center bore sizes

    Weird… When I check the BORA wheel spacer site, it shows the center bore size for GM as 77.8 (same as Dodge Ram), However, when I check everywhere else… It shows up as 78.3. Which is it?

    Question about center bore sizes

    If it was the other way around (larger GM bore size wheel onto smaller Ram hub), what would pose more of an issue… But, I’m thinking the smaller bore size of the Ram wheels was enlarged when the rims were torqued down into the GM hub. Given that they are extra tight… Is it okay to keep...

    Question about center bore sizes

    I bought a set of wheels from friend of a friend a while back, which he told me were “GM bolt pattern” 6 x 5.5 I installed them and they seemed to fit fine. Recently, I noticed my neighbor’s Dodge Ram truck… He has the same wheels… I realized the rims on my truck are from a Dodge Ram! The bolt...

    Any muffler experts here? (Tone of Flowmaster 50 Big Block vs 70 Big Block II)

    Thanks a lot for the feedback. I too don’t want it too loud at all, but would be cool to have a deep tone to it. I’m wondering how similar the 50 BB may sound, give that it has one less delta baffle, and 2” extra in bore case diameter, which in theory should provide for a deeper tone. You...

    Any muffler experts here? (Tone of Flowmaster 50 Big Block vs 70 Big Block II)

    Looking at these photos, I’m questioning whether the interior designs are accurate. Either way, does anyone have any experience with either of these models?

    Any muffler experts here? (Tone of Flowmaster 50 Big Block vs 70 Big Block II)

    As the title suggests, I’m wondering about the tone (not so much the loudness) of the Flowmaster 50 Big Block VS the 70 Big Block II I know that the Flowmaster loudness scale corresponds to the model number (lower number = louder) Yet, somehow the “quietest” Flowmaster (Big Block 50) has a...

    Please help- P0455 Evap Emission

    2004 5.3L Vortec 4x4 So, I’m driving along, and get a warning ding and a message on the cluster that says “Tighten fuel cap” Once, I pull over… I check the fuel cap, it’s tight. I’ve driven 1/2 the tank, so if it were loose, I probably would have received this message sooner, no? Once, I...

    Anyone running a Pro Charger on. 5.3 or 6.0?

    Wondering if anyone here has experience running a Pro Charger on a 5.3 or 6.0 Vortec? If so, what are your thoughts? What worth it? What is your MPG like?

    Used engine flush, now rear main seal leaking.

    Well, good news… After a few days of dripping after each drive, the leak has completely stopped. There is no more dripping. Something to note… I did add a can of Ceratec with the oil change, so maybe that helped? I have also been doing a lot of highway driving this last week, so not sure if...

    Need help… Crank/no start + Really bad MPG

    Update: After a week of driving, the crank/no start issue is still completely, also the average MPG has crawled up to 12.8 (and counting)… much better than 9.2 I have been doing a lot more highway driving this week, so I hope that’s not the only thing that made the MPG jump like this. I’ll...
