Parts for your 2016 Lexus Is-Thrust bearing

2016 Lexus IS thrust-bearing — is it actually a thing?

Short answer: a thrust-bearing isn’t a standalone, serviceable part on the 2016 Lexus IS for Australia and New Zealand. That model range was sold with automatic transmissions only, and the front end uses a double-wishbone suspension design. Both of those points matter, because they remove the two common places people expect to see a “thrust bearing” as a service item — a manual gearbox’s clutch release (thrust) bearing and a MacPherson strut top bearing.

Technical references that back this up include the Lexus IS (XE30) New Car Features manual and the Toyota/Lexus Electronic Parts Catalogue for the 2016 IS line-up, which show:

• No manual transmission fitment in AU/NZ for 2016 IS models (IS 200t/300/350), so there’s no clutch release/thrust bearing to service.
• A double-wishbone front suspension rather than a MacPherson strut, meaning there’s no rotating strut-top thrust bearing in the front shock mounts.
• Any “thrust bearings” that do exist are internal components — e.g., the crankshaft thrust bearing within the engine’s main bearing set, and selective/needle thrust bearings inside the automatic transmission. These are overhaul-only parts, not routine service items.

So if a parts listing shows a “2016 Lexus IS thrust bearing”, it’s either mislabeled, meant for an engine/transmission rebuild kit, or simply not applicable to regular servicing.

Chasing noises that might be mistaken for a failed thrust bearing? On this model, common culprits include front wheel hub bearings (speed-related growl), control arm bushings or ball joints (clunks on bumps or steering), accessory drive idlers (belt-area whir), and engine or transmission mounts (thumps/shudder on take-off). The front top mounts are rubber-isolated supports, not rotating thrust bearings.

For everyday maintenance, there’s no scheduled inspection or replacement of a “thrust bearing” on a 2016 IS. If the engine or transmission ever needs a rebuild, the workshop manual details the relevant internal thrust components, clearances and replacement procedures — work best left to specialists with Lexus/Toyota specs and measuring gear.

• Does a 2016 Lexus IS have a thrust bearing? Not as a separate service part. With no manual gearbox and no MacPherson struts, there’s no clutch release or strut-top thrust bearing to replace. Any thrust elements are internal to the engine or automatic transmission and only addressed during overhauls.
• What noises get confused with a “thrust bearing” issue on this car? Speed-dependent growls are often front wheel hub bearings, clunks under steering/braking can be control arm bushings or ball joints, whirring at the front of the engine could be belt idlers. These are far more likely than a non-existent service thrust bearing.
• Are thrust bearings involved if the engine or transmission is rebuilt? Yes. The engine’s crankshaft has a thrust bearing integrated into the main bearing set, and the automatic transmission uses selective thrust/needle bearings. They’re precision parts replaced during overhaul, not during routine servicing.
