Car Fix DIY Videos

G’day Guy’s and Gal’s

In this video I discuss one of the big issues with the Isuzu Mu-x, Isuzu D-max, Holden Colorado, Holden Trailblazer. The Issue is with the knuckle seal between the CV shaft and the steering knuckle. When the knuckle seal becomes contaminated with water, grime and dust it can dry the seal out. Once the seal dry’s out it causes friction between the seal and the metal dust boot which creates a very annoying singing/ringing sound at highway speeds. This issue with usually start between 80-100km/hr but some times it can start at lower speeds too.

In my video I show to two methods to rectify the Isuzu Mu-x and D-max knuckle seal contamination issue. The two methods involve lubrication the knuckle seals in two different ways. The two methods are –

1. Jack the vehicle up and use some Inox spray lubricant to lubricate the knuckle seals while spinning the wheel.
2. Jack the vehicle up, remove the wheel, hub bolts, hub cover, cv shaft circlip and shims. Pop the CV shaft out of the back of the hub and lubricate the rubber knuckle seal with either rubber grease or HTB bearing grease.

The Issue with the Isuzu Mu-x and the Isuzu D-max is that the hub seals are very vulnerable to getting muddy or dusty. You will sometimes notice this noise after rain and water crossings due to the water from the rain washing away the lubricant on the seals. The squealing sound from the front of the vehicle may start just after a rainy day driving around town.

In my video I give you a thorough DIY Guide to fixing the squealing, singing, ringing hub/knuckle seals. I try to make the video very clear and straight forward so even people without much mechanical knowledge can carry out the repair and get back on the road.

The First method that I demonstrate is more of a temporary repair. Spraying the inox spray behind the hub seals is a quick and easy way to stop the annoying singing, ringing noise at highway speeds. In the long term though the noise with usually always return if you do regular 4WD trips, water crossings, dirt road driving or driving in the rain.

The Second method that I demonstrate is a permanent fix. By packing either HTB Bearing Grease or Rubber grease into the metal dust boot and onto the seal it protects the seal from contamination. The Grease will act as a barrier between water, grime and dust. It will also last a lot longer then the inox spray as it wont wash away easily.

You will require some basic tools to carry out the first method –
1. Floor Jack ( Factory jack OK )
2. Inox lubricant spray
3. Rags for cleaning

You will require some basic tools to carry out this DIY Maintenance repair if you are carrying out the second method, Including –
1. 1/2″ breaker bar
2. 1/2″ short extension
3. 1/2″ 19mm socket
4. 1/2″ 8mm HEX drive
5. Circlip Pliers
6. Floor Jack (factory jack OK)
7. Jack Stands
8. Silicone Sealant or Loctite 515 sealant (Factory sealant loctite 515)
9. Razor blade or wire wheel for cleaning hub sealant
10. Rags and Brake cleaner for cleaning parts
11. HTB bearing grease or Rubber Grease.

Weather you carry out the first repair to the hub/knuckle and CV seals, just ensure that you carry out the same repair to both sides. This will ensure that you will fix your annoying squealing, singing, ringing sound from the front hub seals/knuckle seals. If this video did help you fix your annoying noise, please let me know down in the comments! I’d like to make this video a bit of a talking space for everyone to discuss any issues you may be having with your vehicle. If you can add your opinion, experience or issue to the comments we can all work together to help diagnose and fix all of these annoying issues that our vehicles may have! So leave me a comment and read through the comments to see if you can help fix somebody’s issue too.

I aim to film a few more videos related to Common issues with the Isuzu Mu-x and D-max. This will also apply for Holden Colorado and Colorado 7 because a lot of the parts on these vehicles are the same.

Thanks a lot for watching 🙂 🙂
