First, I got this way faster than I expected. As a result I was able to use it. I first tried just holding my grease gun up to the hole and doing it that way because I needed the truck back on the road but when this came I was able to use it and it was well worth the money and taking off the parts again to use it!! Super easy and way better than just holding the grease gun up to the hole!!! Another Great invention from the group at RiffRaff Diesel!!! Thank you guys!!!

Great idea for hub maintenance.

This is a great tool that I have been without until now. If you have one of these trucks or work on them for a living, this is a great toolbox addition to keep these sealed unit bearings alive.

Fit perfectly. Always have had a good experience with these guys

What a great product. Worked perfectly!!

Wish I would have bought sooner world of difference in my front bearings with a good quality grease

Excellent product and very unique idea and even better it works great!

Works like a charm and lets me grease my ungreasable wheel/hub bearings preventing having to buy a whole new hub...ingenious! Thanks guys

Just did a full brake job, pads, rotors and lubed the un-lubable 4x4 hubs. Best bang for the buck, preventative maintenance tool to get those hubs filled with much needed grease. Great idea, fellas, keep it up.
