Tie rod boots completely split. What all should I replace?

The tie rod boots on my 330xi are both completely split in half and probably have been for quite some time. How do I decide what all to replace? I imagine the boots are there for a reason, so I'm afraid that just replacing the boots will likely mask a bigger problem.

I want the car to last and be reliable so other than being smart about where I buy parts I don't want to go cheap and just slap a band-aid on there.

BTW, I'm also going to be replacing the front axles when I do this work, so I'll already be pulling everything apart.

Thanks for any insight you can provide.

The inner boots are split? Just buy the whole tie rod (inner and outer) plus the end and replace the whole thing. On both sides obviously.

I would say if there's no fluid coming from the boots and there's no lateral play in the rods (easy way to check is push on the inside of the wheels at 3 and 9 o'clock positions) you'd be ok to just replace the boots, there's a tie rod boot kit available for this. Just be sure to check the inner rod / joint, depending on how long the ripped boots have been allowing debris in you might want to replace the inner assembly at the same time.

Good luck!

Thanks for the input. Looks like the tie rods aren't too expensive so I'll just replace everything. Not only are the boots completely split, but if I turn the wheel all the way in either direction I can hear a horrible squeal. From what I've read this is likely due to worn tie rod joints? Anything else I'd be stupid not to do if I'm going to replace axles and tie rods? Bushings were all been replaced a little over a year ago. I'll check them for play, but my guess is they are still good.

you won't get a squeal from worn tie rod ends, or torn boots. the squeal is most likely coming from the power steering pump &/or belt.

Thanks. It didn't make sense to me either, but I seem to recall people talking about it as one of the symptoms.

It is definitely not a belt, but I suppose it could be related to the peer steering pump. Based on when I hear the sound it must have something to do with the steering. What tells the steering that the wheels have turned as far as they can go so it doesn't destroy itself at the full right or left positions?
