The ball on top of the zerk fitting won't seal. Tried to press the ball in a few times with a wire to see if it would reseat itself. No luck. Still oozes grease.

Found the section on replacing zerks in the "Guides" section, but the fittings that were replaced have a hex on them for a wrench.

My fittings on the upper control arm don't have a hex on them.

Should I get on them with vice grips?

Are they pressed in?

How can I replace it?

Hi benex :

 

I replaced mine with a 90 deg. zerk made by Plews. It fit in real well. The threaded portion of the new zerk that went into the housing extends further in than the factory zerk, but that doesn't seem to hurt anything at all.

 

I had to buy a package of 5 of these zerks. It was Plews Product Number 715 - 2018 -- described as "90 deg. Angle Metric Grease Fittings; 6MMXl - 3/4" Overall; Ballcheck."

 

Both the original zerk and the Plews replacement have a hex fitting, but they are different sizes. The original zerk takes an 8mm open box wrench, the Plews replacement needs a 9mm wrench.

 

I just did the same test you did on the "stiffness" of the ballcheck, and the Plews seems much stronger and more positive than the factory zerk. Once you get the switchover done you shouldn't have any more problems with lube oozing back out.

 

All this info. is for a year 2002 1500 4x4 truck. Other models and years may be different.

 

Hope this helps.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
