LG & Kenmore Washer Rear Tub Gasket Parts — Models & Compatibility

When your LG or Kenmore front-load washer starts leaking during spin cycles or making grinding noises, there's a good chance the rear tub gasket has failed. This seal sits between the outer tub and bearing housing — when it goes bad, water reaches the inner bearing, causing rust, noise, and eventually a puddle on your laundry room floor. The MDS62058301 rear tub gasket fits over 50 LG and Kenmore washer models from the WM series, and while it's not a quick fix, replacing it now prevents a much more expensive bearing replacement down the road.

Is This the Right Part for Your Model?

Check the model number plate inside your washer door or on the back panel. This gasket works with LG WM-series front-loaders and their Kenmore counterparts, including popular models like the WM3150HVC, WM3400CW, WM3700HVA, and WM3875HWCA. If you've got a model number starting with "WM" followed by four digits, you're likely in the right place. The compatible list covers models from around 2010-2018, so if your washer is in that range and showing symptoms like leaking or bearing noise, this is your part.

About This Replacement Part

The rear tub gasket creates a water-tight seal between the outer tub and the bearing assembly. When it fails, water seeps past and attacks the steel bearings, causing rust and that distinctive loud grinding noise during spin cycles. One technician described the repair process bluntly: "The shaft was VERY difficult to free from the bearings ... took the heat, penetrating oil, and a sledgehammer." That's because by the time most people replace this gasket, the bearing damage has already started. This is a 2+ hour job requiring serious disassembly — you'll need to remove the tub from the machine, which means disconnecting hoses, freeing the drum, and punching out the old bearings if they're compromised. You'll want an adjustable wrench, socket set, hammer, brass punch, penetrating oil, and patience. Label your hardware in plastic bags as you go; reassembly on these machines is tedious, and missing one hidden screw will cost you an hour of frustration.

Common Failure Symptoms

Water leaking during wash or spin cycles is the most obvious sign this gasket has failed. You might also hear bearing noise — a grinding or rumbling sound that gets louder as the spin speed increases. If you're hearing that noise, act fast: the longer you wait, the more likely you'll need to replace the bearings along with the gasket, turning a $40 repair into a $100+ job. Some owners report water pooling under the washer after heavy loads, which means the seal is completely shot and water is escaping the tub assembly.

Installation Overview

This isn't a beginner repair. You'll disassemble most of the washer to access the rear tub area, including removing the top, front panel, and drum assembly. Once you've got the tub out, you'll see the old gasket seated around the bearing housing. The real challenge comes when freeing the shaft from the bearings — expect to use heat, penetrating oil, and significant force. One DIYer noted: "I punched out the bearings and replaced them with the ones that were sent which by the way I received within a couple of days." If you're going this deep, consider replacing the bearings at the same time even if they seem okay — you're already in there, and new bearings cost less than doing this job twice. Tilting the tub level with the floor helps when reconnecting hoses during reassembly.

Why This Part Fails

The rear tub gasket sits in a high-stress environment: constant spinning, vibration, detergent residue, and water exposure. Over time, the rubber deteriorates and loses its seal. LG's front-loaders from this era are known for bearing failures, and the gasket is usually the entry point for water that ruins those bearings. If you've been using your washer for 7-10 years and it's starting to leak or make noise, this gasket has likely aged out. Replacing it before the bearings go saves you time and money.
