This Repair Fixes A Huge Issue With Lots Of Toyotas On The Road Today

One of the greatest frustrations of any repair is a repair that does not solve a problem…or at least solve it completely. Second to that frustration is when you hear a hum-like sound coming from your Toyota's front end, and the dealership garage either tells you they hear and feel nothing or says something like, "That's normal for a Toyota."

Common Toyota Tacoma, Tundra, and 4Runner Problem

According to a recent Royalty Auto Service YouTube channel episode, the Toyota Tacoma, Tundra, and 4Runner all share a common problem that sometimes confuses both mechanics and their customers―a constant or alternating hum with vibration that can be felt through the wheel or floorboard that manifests at particular speeds…and then goes away at a different speed.

This problem was addressed by the host with a previous repair on a 2015 Tacoma with front end issues that needed major front end repair. After the repairs were completed, the Tacoma operated significantly better; however, the owner noticed a slight hum-like sound with some vibration from the repaired Toyota's front end.

Looking a little deeper into what could be the cause of the noise, the host discovered this is a situation familiar to some years of Toyota models due to one of the most common modifications owners like to do with their Tacoma, Tundra, and 4Runners―put on bigger wheels with a lift kit.

At least one post comment supports this view of what can happen when Toyota owners DIY modify their vehicles:

In other words, you can expect problems to eventually develop when you change the geometry of the axle with the differential that affects the bearing between the two, which is why having your vehicle lifted is one of those jobs best left to a garage that specializes in ensuring that everything is aligned precisely right―especially with a vehicle that is going to see some off-road adventuring.

Follow along with the host as he shows how the hum-vibration was diagnosed and repaired on a 2015 Toyota Tacoma with 4WD. In the video, you will see the following:

1. The importance of using a vibration analyzer to pinpoint a front-end problem.
2. The recommended kit that replaces the problematic axle bearing with a bushing that is a permanent fix.
3. How to remove the old bearing and seal and the tricks to doing it and not cause additional problems.
4. How to install the replacement bushing and new oil seal.
5. The results of a successful repair and retest for front-end vibration elimination.
