TENGMUJX spindle assembly 2-pack for 42" and 48" John Deere decks replaces OEM GY21098/AUC15811 and restores reliable blade rotation.

If your mower deck is showing vibration, uneven cutting or unusual noise, worn spindle assemblies are a common cause. These TENGMUJX replacement spindles are machined to match the mounting and shaft dimensions of the referenced John Deere part numbers, providing a direct-fit upgrade for a wide range of riding mowers and lawn tractors. Sold as a convenient two-pack, they let you replace both sides of a single deck or keep a spare for the future.

Which John Deere models and deck sizes do these spindles fit?

These spindle assemblies are designed to fit 42" and 48" mower decks across many John Deere subcompact and garden tractor models. They align with the OE numbers listed and cover both LA- and D-/E-series machines used with these deck widths.

• Compatible OEM cross-references: GY21098, AUC15811, GY20454, GY20867, GY20962, M149625, GX21694.
• Fits LA models: LA100, LA105, LA110, LA115, LA120, LA125, LA130, LA135, LA140, LA145, LA150, LA155, LA165.

How do these spindle assemblies improve deck performance?

Replacing a worn spindle assembly removes play and reduces wobble, which helps blades track true and cut more evenly. The assemblies are built to withstand mower loads and keep blades rotating smoothly under normal conditions.

• Precision-machined shaft and housing for consistent blade alignment.
• Durable bearings and sealing to resist debris and moisture intrusion.
• Sold as a pair so both sides can be renewed at the same time for balanced cutting.

What should I check before purchasing and installing these spindles?

Confirm your deck size and match one of the listed part numbers or compatible models. Measure bolt pattern and shaft size if possible, and consult your mower’s parts diagram to verify correct placement. If uncertain, compare the old spindle’s shape and mounting holes to ensure fitment.

• Verify deck width is 42" or 48" and review your mower’s parts list.
• Compare bolt pattern, shaft length and diameter with the existing spindle.
• Keep safety gear, proper tools, and a service manual handy for safe installation.
