Wix Power Steering Filter P/N:51418
Wix 57678 power steering filter for the 2019-2021 Mack LR and other vehicles is a heavy-duty cartridge filter that catches debris in the power steering fluid.
A whining pump or heavy steering can mean the filter is restricted. Those signs alone don't prove the filter is the problem, because a low fluid level can cause them too.
Among the many vehicles it fits are the 2019-2021 Mack LR, the 2024 Mack Terrapro and the 2022 Mack Granite, and each takes one filter. If your truck isn't one of these, look up its exact model and engine in the "Vehicles it fits" section.
