DNJ MB950 main bearing set for the 1995-2004 Toyota Tacoma V6 3.4L and other vehicles supports and stabilizes the crankshaft. This DNJ main bearing set, also called crankshaft main bearings, helps the crankshaft turn smoothly under high load.
- Promotes effective engine lubrication and reduces friction
- Upper and lower bearing shells, with thrust bearings on select applications to control crankshaft end play and keep oil clearance
- Bi-metal or tri-metal construction with a steel backing and a copper-lead or aluminum intermediate layer for high load capacity
- Soft overlay such as Babbitt or aluminum-tin for embeddability, less wear and low-friction operation
Quick facts
- Part: DNJ MB950 main bearing set
- Also called: crankshaft main bearings
- Fits: the 1995-2004 Toyota Tacoma V6 3.4L and other vehicles
- Condition: New
Worn main bearings can show up as a knock from the lower engine, a low oil pressure warning or metal particles in the oil. Before you replace a main bearing set, rule out other causes of those signs, such as a weak oil pump or a low oil level, because the same symptoms can come from more than one source.

Frequently Asked Questions
Is this DNJ MB950 main bearing set right for the 2000-2004 Toyota Tundra V6 3.4L?
Yes. DNJ MB950 fits the 2000-2004 Toyota Tundra V6 3.4L, and that engine takes one set. Open the "Vehicles it fits" section for other models and engines.
Does the DNJ MB950 set come with thrust bearings?
Only on select applications. Every DNJ MB950 set has upper and lower bearing shells, and where thrust bearings are included they control crankshaft end play.
What are these main bearings made of?
They use bi-metal or tri-metal designs with a steel backing and a copper-lead or aluminum intermediate layer. The soft overlay is a material such as Babbitt or aluminum-tin.
Can a knock from the bottom of the engine mean worn main bearings?
A knock from the lower engine, a low oil pressure warning or metal in the oil can mean worn main bearings. Oil pressure tests need the engine running, so leave that to a shop.
Does DNJ MB950 interchange with 7114M?
Yes. 7114M is one of the numbers DNJ MB950 replaces; the other cross-reference numbers are on the Interchange line.
