Each package contains the inner and outer bearing\/race pairs required for two axles (four hubs total) and double-lip grease seals designed with a springed lip to retain lubricant. That combination simplifies maintenance, reduces parts hunting, and supplies the compatible components for spindles specified as #84.\u003c\/p\u003e\n\n\u003ch3\u003eWhat parts are included and how do they match my axle?\u003c\/h3\u003e\n\u003cp\u003eThis set contains four inner bearing\/race pairs (L68149\/L68111), four outer bearing\/race pairs (L44649\/L44610), and four double-lip grease seals (10-19, 1.719\" I.D.). The bearings and races correspond to common 3500-lb trailer hub assemblies, and the seals fit hubs that accept a 1.719\" inner diameter part. Always verify your hub and spindle numbers before installation to confirm fit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInner bearings and races: L68149 \/ L68111 (x4)\u003c\/li\u003e\n  \u003cli\u003eOuter bearings and races: L44649 \/ L44610 (x4)\u003c\/li\u003e\n  \u003cli\u003eSeals: double-lip 10-19, 1.719\" I.D., with springed lip (x4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the double-lip grease seal help during towing?\u003c\/h3\u003e\n\u003cp\u003eThe double-lip design provides two barriers against contaminants while the internal spring behind the sealing lip helps maintain contact and keep grease inside the hub. This reduces the chance of premature wear from moisture or dirt exposure and helps prolong bearing life when properly greased and installed. It’s not a substitute for correct maintenance, but it improves protection compared with single-lip seals.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo sealing surfaces for improved contamination resistance\u003c\/li\u003e\n  \u003cli\u003eReinforcing spring keeps consistent lip pressure\u003c\/li\u003e\n  \u003cli\u003eHelps retain lubricant inside the hub during operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat tools and steps are needed to replace these bearings and seals?\u003c\/h3\u003e\n\u003cp\u003eBasic hub servicing requires a jack, jack stands, socket set, bearing packer or grease gun, bearing race driver or press, and torque wrench. Remove the wheel and hub, pull old bearings and races, install the new races (driven square and flush), pack bearings with high-quality wheel grease, fit bearings, and install the new seals. Torque the axle nut per manufacturer spec and check for correct endplay and smooth rotation before the first trip.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEssential tools: jack, stands, sockets, race driver\/press, grease packer\u003c\/li\u003e\n  \u003cli\u003eStep highlights: remove hub, replace races, pack bearings, press seal, set torque\u003c\/li\u003e\n  \u003cli\u003eConfirm spindle type (#84) and follow vehicle-specific torque\/endplay values\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these kits work for routine maintenance or emergency replacements?\u003c\/h3\u003e\n\u003cp\u003eYes — the kit covers both planned overhauls and roadside repairs when you have time and tools. Having a complete set on hand makes it faster to perform scheduled bearing service or to address bearing failures by replacing both bearings, races, and seals together.
