Z4M tie rod replacement - outer end only?

Post by pcube » Mon Jun 26, 2017 3:40 pm

While my car was up on jacks I noticed that the front right wheel had some lateral free play, which suggests that the tie rods need replacement.

Looked up realoem, and realised that there is no part number for the inner tie rod, only the outer one or the whole assembly (inner and outer with new nuts). Searched several online suppliers, and confirmed that it is not possible to purchase the inner tie rod separately.

So that got me thinking, perhaps it isn't necessary to replace the inner ones? What have you guys been doing? Replacing the whole assembly, or only the outer tie rod end?

Additional note: whole assembly is sold as original bmw (no oem alternatives) so rather expensive. Oem outer tie rod ends are available from Lemforder, which are much more affordable.

I replaced the whole assembly with Lemforder parts but mines not an 'M' so may be different?

Although I'm speaking from non-M experience here, I think most people replace the full rod due to the corrosion and rust that develops where they join. I know from my experience that the toe adjustment would not move, and I had to cut it with a grinder to get the dust boot off for the new ones.

I'm not sure if the M has a different (read: better and less prone to rusting!) design, so it may be a lot easier for you to get them apart.

Following with interest.
After replacing most of the front suspension on my M I got an advisory on the tie rod having play.
BMW parts where bloody expensive, and as the play was minor I've not done anything about it.

Be interested to know how you get it sorted.

Tie rod ends you might have got, ECP didn't do the whole rod last time I checked.

It was the Rod I'm pretty sure, it's called an Axial Rod on the invoice, they've gone up now from £23.10 to £40.99

Z4M tie rod replacement - outer end only?

The joint between the inner and outers can be a pain. Prior to going for alignment, because I didn't want them using heat, I loosened the locking nuts and gave them a good spray of PB Blaster, and then using a flat ended bar in the air impact chisel, I put it against the bit that is slotted and threaded on the inside, and vibrated the hell out of them for a coupe of minutes, more spray and left them loose overnight. Next morning they turned easily, so nipped the locknuts up and went for the alignment. He commented that they are usually barstewards, but mine adjusted easily..

Darren, that's only the inner tie rod end. So odd that there's an oem part when BMW doesn't even have a part number for it. I assume you had to buy the outer end separately? Everything fits without issue? If it does, this is an awesome find. I've searched through all the major online parts suppliers based in the US, and there is no option to have the entire tie rod replaced with oem.

Most of the articles or opinions I've read that recommended changing the inner end at the same time cited reasons relating to seized bolts. None of them ever mention that the joints on the inner end wearing. So it's more just to avoid the hassle? No real necessity?

I'm doubting myself now.

Was it the same part number for each side???? Its only listed for the drivers side on the ECP Site
If it was then I'll order some!

Edited to add, looking at other sites the inner isn't side specific, and can get all 4 parts from carparts4less for under £100...........

Hi, I only bought the Inner's the outer were all good, it was 3 years ago tbh and I like Malbec so the brain cells have degenerated!

I must have had some play in them I'm assuming :thumbsup:

Reassuring to have someone verify that the part fits, thanks!
