Buying Drivetrain Parts for a 1973 Checker Taxicab
On this vehicle, the drivetrain system moves power from transmission to wheels through axles, CV joints, driveshafts, differentials and wheel-end hardware.
- Match the engine first. Some drivetrain parts fit every engine; others are engine-specific. Each row shows which engine(s) it fits.
- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace the differential or transfer-case fluid with any axle or seal job while everything is already open.
- Cross-reference the manufacturer part number against your old part or a service-manual listing.

Frequently Asked Questions
How many drivetrain parts fit the 1973 Checker Taxicab?
Our catalog currently lists 58 drivetrain parts for the 1973 Checker Taxicab across 10 subcategories and 13 brands, covering both the 4.1L 250cid L6 and the 5.7L 350cid V8. Each part is matched to the engine(s) it fits.
Do drivetrain parts differ between 1973 Checker Taxicab engines?
Some do. 31 parts fit every engine; the other 27 are engine-specific. Each row (and the filter at the top) shows which. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of drivetrain problems on a 1973 Checker Taxicab?
Common symptoms include clicking in tight turns, a clunk when shifting between drive and reverse, vibration that builds with speed, or gear oil on the inside of a wheel. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, replace the differential or transfer-case fluid with any axle or seal job while everything is already open.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 1973 Checker Taxicab was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 1973 Checker Taxicab?
First match the engine — each row shows which engine(s) the part fits. Then a torn CV boot caught early is a cheap boot kit; caught late it is a whole axle — inspect before deciding which to buy. The notes column carries position and trim qualifiers where they apply.
