Project: 2018 RAV4 Brake Overhaul & Handling Fix

Project Summary

My 2018 RAV4 was starting to show its age, specifically in how it stopped and how it sat. Between worn-out brakes and a sagging rear end—made worse by a tow hitch and the constant leverage of a loaded bike rack—the car felt sluggish and unrefined. I took this on as a "refresh" project to restore safety and upgrade the handling beyond factory specs.

Problem

The car was facing two main issues that were affecting daily drivability:

  • Safety: The front and rear brakes (both pads and rotors) were at the end of their life cycle, leading to diminished stopping power.

  • Stability: The rear suspension was "squatting" under the combined weight of a factory tow hitch and the added leverage of a bike rack. This sagging made the steering feel light and the handling unpredictable over bumps and highway expansion joints.

Approach

I realized that simply throwing stock parts back on wouldn't solve the "sag" problem. I needed a solution that accounted for the extra weight hanging off the back. After some research, I chose the Bilstein B6 4600 series shocks. These are high-pressure gas units designed to provide better control and support for vehicles carrying extra loads, making them the perfect analytical choice for a car that actually gets used for gear.

Solution

  • Brakes: I performed a full four-corner overhaul, swapping in fresh rotors and pads to ensure the friction surfaces were perfectly matched for maximum bite.

  • Suspension: I pulled the tired factory shocks and retrofitted the Bilstein B6 units. This wasn't just a repair; it was a targeted upgrade to handle the extra vertical load from my bike rack.

Outcome

The difference was night and day. The RAV4 now sits level again—even with the bikes loaded up—and the "planted" feeling on the road is actually better than when it was brand new. By diagnosing the root cause of the poor handling and choosing the right gear for the job, I turned a standard maintenance task into a major performance win.

Project: Dishwasher Circulation System Recovery

Project Summary

When my 5 year old dishwasher stopped mid-cycle and refused to wash, it presented a classic "replace vs. repair" dilemma. Instead of junking a high-end appliance, I treated it as a systems-failure puzzle. I performed a full teardown to the chassis level to diagnose why the circulation system had reached a total standstill.

Problem

The unit suffered a primary system failure: while the dishwasher would fill and drain, it would not actually wash. The circulation motor had seized completely, meaning no water was being pushed through the spray arms. This left the unit non-functional and required a deep-dive into the internal assembly to identify the mechanical bottleneck.

Approach

I took an analytical approach to isolate the failure, stripping the unit down to the chassis to determine if the issue was a logic board error or a hardware seizure. After confirming the motor was receiving power but failing to turn, I sourced the exact OEM replacement—Pump and Motor Assembly WPW10605057—to ensure the replacement met the original factory flow-rate and pressure specifications.

Solution

  • Mechanical Overhaul: I performed a surgical removal of the seized motor and pump housing. I then retrofitted the new WPW10605057 assembly, carefully routing the wiring harness and seating the high-pressure seals.

  • System Calibration: Once the new motor was in place, I cleaned the internal housing and verified the float switches and drainage sensors to ensure the system logic was perfectly synced with the new hardware.

Outcome

The dishwasher was restored to 100% operational capacity, running as quietly as the day it was bought. By diagnosing the specific hardware failure and executing the repair myself, I avoided a $1,000+ replacement cost and kept a major appliance out of the landfill. This project was a perfect exercise in identifying a mechanical failure and executing a high-precision fix.
