Toyota Supra Universal Joint Replacement Guide (1986-1993)
Addressing vibrations and clunks from your A70 Supra's driveline starts here.
- Factory U-joints are 'staked-in' and require a machine shop to press out and replace.
- Symptoms progress from squeaking noises to vibrations and clunking sounds.
- Spicer is the most recommended brand for durability; GMB and SKF are reliable OEM-style alternatives.
- It is critical to have the driveshaft balanced after replacing the U-joints to prevent vibrations.
Is Your Supra Making Strange Noises?
A failing universal joint will give you clear warning signs. The earliest symptom is often a faint, rhythmic squeaking noise at low speeds as the internal bearings lose their grease. As the wear gets worse, you may feel a vibration throughout the car, especially at highway speeds. A distinct “clunk” or “ping” when you shift from park into drive or reverse is another classic sign of a worn U-joint with too much play. If you ignore these symptoms, the U-joint can fail completely, potentially causing the driveshaft to disconnect from the vehicle.
A Critical Note on Supra U-Joints: Staked vs. Serviceable
The original U-joints on your 1986-1993 Supra's driveshaft are likely "staked-in." This means the factory did not use clips to hold them in place; instead, the metal of the driveshaft yoke was pressed or peened over to secure the U-joint caps. This makes replacement much more difficult than on other vehicles. You cannot simply unbolt clips and swap the part. The staked material must be precisely ground or machined away, and the old joint pressed out. Most aftermarket U-joints for your Supra are a serviceable design with C-clips. While a skilled DIY mechanic with a hydraulic press can perform this job, it is highly recommended to remove the driveshaft yourself and take it to a professional driveline or machine shop. They can press out the old joints, install the new ones, and balance the entire assembly, which is critical for preventing vibrations.
Choosing the Right Aftermarket U-Joint
Since original Toyota U-joints can be expensive or hard to find, the aftermarket offers several good options. They generally fall into a few quality tiers.
Premium Tier: Best for Performance and Durability
- Dana/Spicer: Widely considered the gold standard by mechanics and enthusiasts. Spicer parts are known for being incredibly strong and durable. Their non-greaseable, cold-forged joints are often considered their strongest option and are a great choice for both stock and modified Supras.
Standard Tier: Reliable OEM-Style Replacements
- SKF: Known globally for high-quality bearings, SKF is a trusted name. While not as commonly discussed in forums as Spicer, their reputation for precision manufacturing makes their U-joints a solid and reliable choice.
- GMB: GMB is a Japanese manufacturer and a known OEM supplier for various car brands. They are a very popular and dependable choice for a stock replacement that meets or exceeds original quality without the premium price tag.
Economy Tier: Budget-Friendly Options
- Moog: Moog used to be a top-tier name, but in recent years, owner reviews have become very mixed. Many report a decline in quality, with parts being re-boxed from various sources. While they may be a budget-friendly option, they are often not recommended by enthusiasts for long-term reliability compared to Spicer or GMB.

Frequently Asked Questions
How many U-joints does my Supra have?
Your Supra has a two-piece driveshaft. It will have a U-joint at the transmission, one at the rear differential, and one connecting the two halves of the driveshaft near the center support bearing. You should plan to replace all of them at the same time.
Should I get greaseable or non-greaseable U-joints?
Non-greaseable (sealed) joints are generally considered stronger because the cross body is solid metal. Greaseable joints have channels drilled into them for the grease, which can be a minor weak point. For most Supras, a high-quality sealed joint like a Spicer is preferred for a fit-and-forget installation. Greaseable joints require periodic maintenance but can last a long time if cared for.
Were there any recalls for the Supra's U-joints?
No. There have been no recalls or common Technical Service Bulletins (TSBs) issued by Toyota or the NHTSA for universal joint failure on the 1986-1993 Toyota Supra. This is considered a normal wear-and-tear item.
Can I just replace one bad U-joint?
While you can, it is highly recommended to replace all U-joints at the same time. They have all experienced the same amount of wear and mileage. If one has failed, the others are likely near the end of their service life. It is more cost-effective to have them all pressed and the driveshaft balanced in a single visit to the shop.
