Parts for your 2020 Ford Transit-Universal joints

2020 Ford Transit universal joints: what they do, when to service, and how to spot trouble

Yes, the 2020 Ford Transit uses universal joints (U-joints) on rear‑wheel drive and all‑wheel drive variants. This is confirmed by Ford’s technical literature for the 2020 Transit driveline/propeller shaft assembly (Ford Workshop Manual, Driveline/Driveshaft section) and corresponding Ford service parts catalog illustrations, which show cross‑type U‑joints integrated with the prop shaft. On front‑wheel drive platforms, constant‑velocity (CV) joints are used at the front axles instead, but the full-size 2020 Transit commonly seen in Australia and New Zealand is RWD or AWD and therefore uses U‑joints on the tailshaft.

On this model, the U‑joints sit at each end of the propeller shaft, allowing it to transmit torque at changing angles as the rear suspension moves. Their job is simple but critical: keep the driveline smooth, strong, and quiet from the gearbox to the rear diff. Many factory Transit shafts are supplied as “non‑serviceable” assemblies in Ford documentation, meaning the U‑joints aren’t listed as standalone service parts, in practice, workshops either replace the complete shaft or fit quality aftermarket serviceable U‑joints where appropriate and to spec.

For servicing, regular inspection is key. Even sealed‑for‑life joints can wear if boots are torn or water and dust get in. Aftermarket greaseable joints, if fitted, benefit from periodic greasing with a quality lithium‑based grease at routine service intervals.

• Common signs it’s time for attention:
  • Clunk when shifting from drive to reverse
  • Vibration under load or at highway speeds
  • Chirping or rumbling that changes with road speed
  • Visible play or rusty dust around the bearing caps
• Good workshop practice on a 2020 Transit:
  • Check U‑joints and the centre support bearing together
  • Mark flanges before removal to preserve phasing and balance
  • Use new flange bolts where specified and tighten to the correct torque
  • If the joint is staked/non‑serviceable, replace the shaft or use an approved repair method

Left too long, a failing U‑joint can damage the yokes, centre bearing, and even the transmission output seal. A quick check at each service, plus prompt replacement when symptoms show up, keeps the Transit driving tight and tidy on Aussie and Kiwi roads.

Popular questions

How often should U‑joints be checked on a 2020 Transit?

At every routine service or tyre rotation, have the driveline inspected for play, leaks, and noise. If the vehicle tows, carries heavy loads, or drives on rough roads, more frequent checks are smart. Greaseable aftermarket joints should be lubricated at the same interval.

Can the U‑joints be replaced without changing the whole driveshaft?

Many OEM shafts are documented as non‑serviceable, so Ford supplies the shaft as an assembly. However, specialist driveline shops can often replace worn joints with high‑quality serviceable units and rebalance the shaft. It comes down to the specific shaft fitted and workshop capability.

What happens if a worn U‑joint is ignored?

Vibration and clunks usually get worse, potentially taking out the centre bearing, damaging yokes, and stressing the transmission and diff. In extreme cases a joint can fail and the shaft can separate, which is unsafe and expensive. Early repair is cheaper and safer.
