Frequently Asked Questions
How many drivetrain parts fit the 1964 Triumph TR4?
Our catalog currently lists 29 drivetrain parts for the 1964 Triumph TR4 across 5 subcategories and 10 brands, covering both the 2.0L L4 and the 2.1L L4. Each part is matched to the engine(s) it fits.
Do drivetrain parts differ between 1964 Triumph TR4 engines?
Yes. Every drivetrain part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. 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 1964 Triumph TR4?
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 1964 Triumph TR4 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 1964 Triumph TR4?
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.
