Is it necessary to replace the electronic steering gear if it gets water inside?
2 Answers
It is not always necessary to replace the electronic steering gear if it gets water inside. As long as the dust cover of the steering gear tie rod is not damaged, it will not affect normal use, and no water will enter. If there is water inside, dry it out and apply grease for maintenance. Below is an extended introduction: 1. Inspect the steering gear: Regularly check the condition of the protective covers on both sides of the steering gear and the protective cover connecting the upper part of the steering gear to the universal cross joint. Damage to the protective covers is the main factor leading to early wear and damage of the steering gear. Once the protective cover is damaged, water, dust, and sand can enter the steering gear through the damaged area, destroying the lubricating grease film on the gear rack, leading to internal rust and abnormal wear. 2. Recommendation: If the internal water and sand are not removed immediately, the steering gear may be rendered useless in a short time. Therefore, inspect the condition of the dust cover at least once a month. If any damage is found, replace it immediately and conduct a comprehensive inspection and maintenance of the steering gear before replacement.
Electronic power steering doesn't necessarily require immediate replacement after water ingress - it depends on the specific situation. Once when my car went through water, the steering became less responsive. After inspection at the shop, the mechanic said water exposure could cause motor short circuits or sensor failure. They disassembled, cleaned, dried it thoroughly, and after functional testing confirmed it worked normally, saving replacement costs. If water only reached surface areas, promptly disconnecting the power and using a hair dryer or natural drying may suffice. However, with deep water exposure or signs of corrosion where components are damaged, replacement becomes mandatory to avoid steering failure risks while driving. Additionally, such electronic component water damage commonly occurs when fording deep water during heavy rain, so avoid flooded sections when possible and routinely check sealing rings. When uncertain, always seek professional diagnosis at repair shops - safe driving should always come first.
