Hudson Super Jet Universal Joint Replacement Guide (1954)
Everything you need to know about replacing the universal joints on your 1954 Hudson Super Jet.
- U-joint failure gives clear warnings like clunking, vibrations, or squeaking.
- New OEM parts are not available; choose between quality aftermarket brands like Moog or GMB.
- Replacement is possible for a skilled DIYer but requires a bench vise or press for proper installation.
- If you hear or feel symptoms, get the U-joints inspected to avoid a complete failure and driveshaft separation.
Symptoms of a Failing Universal Joint
A worn-out U-joint will give you clear warning signs. Because parts for the Super Jet can be hard to find, it's best to address these symptoms early before more damage occurs. Listen and feel for these common signs:
- Clunking Noise: A sharp "clunk" or "ping" when you shift from Drive to Reverse (or vice-versa) is a classic sign. This is the sound of excessive play in the joint.
- Vibration at Speed: A vibration that gets worse as you drive faster can be caused by a worn U-joint. It may feel like it's coming from the center or rear of the car.
- Squeaking or Chirping: A rhythmic squeak that matches the speed of your driveshaft (not the engine) points to a dry, failing U-joint bearing.
Choosing the Right Aftermarket U-Joint
For a 1954 vehicle, finding new original equipment (OEM) parts is nearly impossible. The market consists of new aftermarket replacements. For your Super Jet, two common brands are GMB and Moog.
Brand Tiers & Quality
- Moog: Often seen as a premium or "problem-solver" brand in the aftermarket world. Moog U-joints are typically greasable, which allows you to flush out old grease and contaminants, potentially extending the part's life. However, some classic car owners have mixed opinions on modern Moog quality, suggesting it can be inconsistent.
- GMB: GMB is a well-regarded Japanese manufacturer that produces quality bearings and U-joints, often for original equipment manufacturers. They are generally considered a reliable, standard replacement part that meets or exceeds original specifications.
Pro Tip: Greasable vs. Non-Greasable
Some mechanics prefer solid, non-greasable U-joints, believing their solid cross design is stronger. Others prefer greasable joints for their serviceability. For a stock Hudson Super Jet, either type will perform well. The most important factor is correct installation.
Typical Replacement Costs
The cost for a new aftermarket U-joint is low, but labor can add to the total if you have it done professionally. The job requires special tools like a bench vise or a hydraulic press to do correctly.
| Part Type | Price Range |
|---|---|
| New Aftermarket U-Joint | $17 - $29 |
| Shop Labor | $100 - $250 |
A Note on Known Issues
No official recalls or technical service bulletins (TSBs) exist for the 1954 Super Jet's U-joints, as modern record-keeping by agencies like the NHTSA started much later. However, anecdotal reports from Hudson enthusiasts suggest that cars from this era equipped with more powerful engines could be hard on U-joints. Regular inspection is recommended.
Frequently Asked Questions (FAQ)
How many U-joints does my 1954 Super Jet have?
Most 1954 Hudson Super Jets with a single-piece driveshaft have two universal joints: one at the transmission end and one at the rear axle end. It is recommended to replace them in pairs.
Can I replace a U-joint myself?
This is a DIY-feasible job, but it requires more than basic hand tools. You will need to safely raise the vehicle, remove the driveshaft, and use a powerful bench vise or a hydraulic press to push the old joint out and the new one in without damaging the driveshaft yokes. A service manual for the Hudson Jet provides a basic procedure.
Are original Hudson U-joints available?
New Old Stock (NOS) parts are exceptionally rare and expensive. For a wear item like a U-joint, a new aftermarket part from a quality brand is the most practical and reliable choice.
What happens if a U-joint fails completely?
Complete failure is serious. The U-joint will break, and the driveshaft can detach from the car. This will cause a total loss of power to the wheels and can cause significant damage to the underside of your vehicle when the driveshaft falls and hits the road at speed.
