Ever wonder what the engineers were thinking when they located the grease fittings on your vehicle? Me too.
For example, how are you supposed to get at a straight fitting on the idler arms that have no clearance above them? Forget using a standard coupler or even a swivel head coupler. After stewing about it for a while, I googled “right angle grease gun fitting” and found a coupler like the one above. A little more searching and I found a cheap one on Amazon that I could have in a few days.
The hardened steel coupler fits all standard grease guns — unscrew the standard coupler and screw this one in it’s place. Then, rather than pushing this coupler onto the zerk fitting, you slide it sideways onto the fitting until it stops.

If you still aren’t sure how this coupler connects to a zerk fitting, Thexton has a YouTube video showing how to use it.
I’ve tackled these two hard-to-reach fittings on my truck before. Last time, I needed the help of my father-in-law to line up the steering wheel while I crawled in the top of the engine compartment with a double length grease gun hose. I figured there had to be a better way.
It’s frustrating that Chevy decided to put a straight fitting in this location. If they would have used a right angle fitting, you could access it when you were greasing the other fittings in the wheel well. I know I could just replace the fitting, but I worry that I’d do more damage by contaminating the joint with the 15 years of dirt and rust under the truck.
I ordered one of these Thexton right angle couplers and will let you all know how well it works.
