One-sentence answer:
A drive shaft assembly is built from a tube plus interfaces and articulation parts such as yokes, flanges, U-joints or CV joints, and a slip spline. Some two-piece designs also use a center support. These parts work together to transmit torque while allowing movement in the driveline. [S1][S2]

Quick parts map: what’s inside a typical drive shaft assembly
A “drive shaft” may be a complete assembly or a partial module. The illustration below shows the most common part families procurement teams will see in drawings and BOMs.
Procurement note: Don’t assume two suppliers use the same names for the same interface. Always align on interface geometry (bolt pattern/pilot/spline) and joint family, then map part names.
Drive shaft parts list (what each component does)
This list focuses on what the part is, why it exists, and what to provide for quoting. It intentionally avoids failure diagnostics (covered on the symptoms page) to prevent topic overlap. Tip: click a header to sort
| Part | Primary function | Common variations | Buyer notes (what to specify) |
|---|---|---|---|
| Tube / shaft body | Provides the rotating structure that carries torque between ends. [S1][S2] | Steel or aluminum; different OD/wall; multiple lengths | Installed length method + tolerance; tube OD/wall/material; coating requirement |
| Weld yoke / end yoke | Connects tube to joint or flange; transmits torque at the end interface. | Weld-on vs forged; different U-joint series compatibility | Yoke series/family; critical dimensions; compatibility with joint type |
| Flange yoke / companion flange | Bolt-on interface to differential/transfer case input/output. | Different bolt patterns, pilots, offsets, and flange types | Bolt circle, hole size/count, pilot diameter, flange thickness/offset |
| Universal joint (U-joint) | Allows angular motion while transmitting torque. [S1] | Different series; greasable vs sealed; strap/bolt retention styles | Series/spec; cap diameter/width; retention type; service requirement |
| CV joint / constant-velocity joint | Maintains smoother torque transfer at varying angles vs non-CV in many designs. [S2] | Different CV families; tripod/ball types; booted assemblies | CV family/model; boot spec; grease type; interface on both ends |
| Slip joint / slip yoke / spline | Provides axial movement (“plunge”) as suspension distance changes. [S1] | Internal vs external spline; different tooth counts and travel | Spline count; major/minor diameter; required travel; sealing requirement |
| Center support bearing (carrier bearing) | Supports a two-piece driveshaft and reduces shaft span; mounted to a bracket. | Rubber-isolated vs rigid; different bearing IDs and bracket styles | Bearing ID/OD; bracket pattern; isolation type; alignment constraints |
| Center bearing bracket / mount | Fixes center support to chassis; sets driveline alignment. | Stamped vs cast; different mount offsets | Mounting hole geometry; offset/height; permissible movement; material/coating |
| Balance weights | Corrects imbalance to reduce vibration (NVH). | Weld-on tabs vs clip weights; different correction methods | Balance tolerance; test speed; correction method; marking/traceability |
| Damper / tuned mass damper (if used) | Reduces specific vibration modes and noise in certain platforms. | Rubber ring, mass damper, bonded components | OEM requirement only; position on tube; adhesive/bond spec if applicable |
| Dust shield / heat shield (if used) | Protects joints from debris/heat exposure in harsh environments. | Metal shield vs composite; different mounting styles | Required coverage; mounting method; operating temperature exposure |
| Fasteners & retention hardware | Secures flanges/yokes and joint caps to mating components. | Straps, U-bolts, flange bolts; locking features | Thread spec; torque spec; coating/locking requirement; reuse policy |
Joint families you’ll see on drawings (U-joint vs CV)
Most sourcing confusion happens around joint family and end interfaces. Use the table below to align on the joint type before requesting a quote.| Joint family | Why OEMs choose it | What to specify in an RFQ |
|---|---|---|
| U-joint | Simple, widely used, serviceable in many designs; supports angular movement. [S1] | Series/spec (cap dia/width); retention style; greasable vs sealed; mating yoke family |
| CV joint | Often used to improve smoothness across varying angles and reduce certain vibration modes. [S2] | CV family/model; boot + grease requirements; interface details both ends; plunge (if integrated) |
End interfaces: yoke vs flange (what matters for quoting)
For buyers, the most important thing is not the part name—it’s whether the end interface is a flange, yoke, or CV interface, and what geometry it uses. High-impact: pilot diameter + bolt circle + offset
| Interface type | Where it connects | Critical dimensions | Buyer input examples |
|---|---|---|---|
| Flange | Differential/transfer case mating flange | Bolt circle (BCD), hole count/size, pilot (register) dia, thickness, offset | “4-bolt flange, pilot Øxx, BCD Øyy, offset zz” + photos/drawing |
| Yoke | Captures U-joint bearing caps (strap/U-bolt retention) | U-joint series, cap dia/width, retention style, ear thickness | “1350 series yoke” or exact cap dimensions + retention type |
| Spline / slip yoke | Slides over mating shaft to allow axial movement | Spline count, major/minor dia, pressure angle, travel, seal surface | “xx splines, required travel mm” + mating shaft details |
| CV interface | CV joint to flange/yoke module | CV family/model, bolt pattern/pilot (if flange), boot clearance | CV joint model + end geometry; include boot spec and grease requirement |
Two-piece driveshaft parts (center support system)
Two-piece assemblies add a center support bearing (carrier bearing) and bracket/mount. These parts affect packaging and alignment—and they are common sources of RFQ ambiguity.- Center bearing supports the shaft and may include an isolator.
- Bracket/mount sets position and alignment; offset and hole pattern are critical.

What to Prepare Before Ordering Each Part Group
This table shows the key details that help suppliers identify the correct drive shaft parts. If you can provide the important items in each category, the supplier can usually check fitment faster and reduce follow-up questions.
Goal: reduce RFQ cycles
| Component group | What to provide | Priority | Notes |
|---|---|---|---|
| Overall assembly | Installed length method + tolerance; front/rear location; 1-piece vs 2-piece | Critical | Photos + drawing reduce misinterpretation |
| End interfaces | Flange pattern/pilot/offset OR yoke series/retention; mating component details | Critical | Interface mismatch is the most common quoting blocker |
| Joint family | U-joint series (cap dia/width) OR CV family/model; serviceable vs sealed | Critical | Include boot spec & grease requirement if CV |
| Slip spline | Spline count + diameters; required travel; seal surface | High | Especially important on off-road or high-travel applications |
| Tube | Material; OD/wall; corrosion protection | High | Steel vs aluminum impacts mass and dynamics |
| Center support (2-piece) | Bearing ID/OD; bracket pattern/offset; isolator type | High | Confirm bracket geometry and mounting direction |
| NVH targets | Balance tolerance; runout limits; damper requirement (if any) | Medium | Specify test speed or acceptance criteria if available |
| Hardware | Fastener specs; locking/coating; torque requirements | Medium | Clarify whether bolts are included with the assembly |

FAQ (parts-focused)
What are the parts on a drive shaft?
Most assemblies include a tube (shaft body), end interfaces (yokes and/or flanges), a joint family (U-joint or CV joint), and a slip spline for axial movement. Two-piece designs add a center support bearing and bracket. [S1][S2]What is a slip yoke on a driveshaft?
A slip yoke (or slip spline) is a splined interface that allows the driveshaft to change length as the suspension moves. For RFQs, the key fields are spline count/diameters and required travel. [S1]What’s the difference between a yoke and a flange?
A flange is a bolt-on plate-style interface defined by bolt circle and pilot diameter; a yoke typically captures U-joint bearing caps and is defined by U-joint series/cap dimensions and retention style.What is a carrier bearing (center support bearing)?
It’s the bearing used to support a two-piece driveshaft assembly. Buyers should confirm bearing size plus bracket geometry/offset and whether the mount includes an isolator.Do all driveshafts have U-joints?
No. Many designs use U-joints, but some use CV joints or other couplings depending on NVH and angle requirements. [S2]Where can I request a drive shaft quote?
