Seeking Advice on E90 M3 Rear Hub Splines

I’ve recently been diving into some work on my E90 M3, and I’ve hit a bit of a snag with the rear hub splines. I’ve heard that the splines can be a tricky point in the hub assembly, especially when it comes to compatibility with aftermarket parts or during installation/removal of the rear axles.

What I’m Dealing With:

  • Installation Challenges: I’m struggling to get the hubs aligned properly during installation. Are there any tips or tricks that can make this smoother?
  • Part Compatibility: I want to make sure that any aftermarket parts I’m considering will fit well with the original components. Has anyone had success with specific brands or models?
  • Troubleshooting: If anyone has dealt with issues like noise or wheel wobble after working on the hubs, I’d love to hear your experiences.

What I’ve Tried:

  • I’ve checked the service manual, but some of the guidance feels overly technical.
  • I’ve also watched a couple of DIY videos, but hands-on experiences seem to vary.

Final Thoughts:

If you’ve done work on the rear hub splines or have advice on what to watch out for, I’d appreciate your input! What are the common pitfalls to avoid? Any specific tools that made the job easier?

Thanks in advance for your insights!

I’ve noticed some issues with the rear hub splines on my E90 M3. They’re designed to fit snugly, but wear and tear can be real problems. Has anyone else experienced this?

Absolutely! The rear hub splines on the E90 M3 are crucial for connecting the wheel to the axle. Compared to other models, they’re more robust due to the higher performance specifications.

I agree with julie38. If the splines wear down, it can lead to uneven tire wear and alignment issues. Be sure to look for any signs of wear when inspecting them.

That’s a valid point! Also, it’s worth checking if the hub bolts are properly torqued. Loose bolts can exacerbate spline wear.

Exactly! I’ve seen splines on other BMW models that tend to be less prone to wear. It seems like the E90 M3 is a bit more sensitive. Anyone else feel this way?

Wow, 40k miles seems early! I’ve read they can last longer with the right maintenance. Have you considered changing the lubricant on them?

Good tip! Also, don’t forget to check your wheel bearings. They can impact the splines too.

Does anyone have photos of the splines, so we know what to look for? I’d like a visual reference when I inspect mine.

I can look for some. Meanwhile, be cautious; a worn spline can lead to wheel detachment in severe cases!

A little humor here — ever tried to explain spline wear to a non-car person? It’s like trying to discuss quantum physics with a cat!

Haha, right? But seriously, the design of the E90 M3 splines is intricate. It’s vital to keep them in check for performance.

I had a similar issue, and it turned out my hub splines were worn down. Make sure to check for any play in the rear wheels, that can indicate spline issues.

I think the handling issues are really common with the E90 M3. It could also lead to uneven tire wear. It’s worth getting them checked out ASAP.
