Hub - Left half
Left half of the front wheel hub assembly, also known by its earlier factory number 37-4126.
37-7058 is the left half of the front wheel hub, part of the front hub assembly on bikes that use a two-piece hub construction. It shows up under the FRONT WHEEL figure in the parts books and carries forward from the earlier number 37-4126, which is the same physical piece under its older factory designation.

The left and right hub halves bolt together around the front wheel bearings and spindle, and this is the left-side casting of that pair. If you're rebuilding a front hub or replacing a cracked or worn half, matching the correct side matters, and it helps to have your old part in hand or your parts book open to confirm you're ordering the right one.
Our catalog record ties this to front wheel work across the 1979 to 1985 span of appearances, but we'd rather you check it against what's actually on your bike than assume. Call the shop if you're not sure which hub half you need or whether 37-7058 or 37-4126 is what your book calls for — they're the same part.
