If you need everything for your front hub, then this is the best deal. This kit is for ONE SIDE ONLY. Comes with inner and outer wheel bearings, seal, cap, ground clip, and pre-load adjusting bolt. Fits the right or left side of all 116 and 123 up to 1985, and 126 chassis up to 1984 ONLY (without ABS). These are VERY common wear items on all older chassis that I see come into the shop. Replace at 150,000 miles.
If you would like information on how to remove the front hub to get to the bearing assembly, refer to my Brake Component Manual. Sorry, but no specific instructions are available for the actual replacement of the bearing. If you need wheel bearing instructions and a removal tool, please see the related products below.
