Let me tell you, this Tiger Tool U-Joint Service Kit is no joke. I've been using it on my Class 8 Freightliner for about three months now, and it's handled every stubborn u-joint like they were made of butter. The removal tool (that 10102 part) has this satisfying *crack* when it breaks loose seized joints - music to any mechanic's ears.

What really surprised me was the bearing cap installers. That 10217 model fits Dana/Spicer joints like it was custom-machined for them - no more hammering caps crooked or damaging seals. Did a full driveline service last week and saved at least an hour compared to my old makeshift tools.

The kit lives in a grease-stained Pelican case in my service truck now. Used it in -20°F Wyoming winters and 110°F Arizona heat - no issues with the tools warping or handles getting brittle. Only gripe? Wish they included a second removal tool so I could keep one at the shop.

Pro tip: Watch their YouTube channel for demo videos. Learned some clever tricks for dealing with rusted-out Peterbilt joints that aren't in the manual. This isn't cheap, but neither are downtime hours when you're fighting with inferior tools.
