Wheel alignment

[stiaan]

Hi guys, I noticed a strange thing this morning, my front tyres on my 320i E90 is becoming like waves on the sides, like wheel alignment not right
10 000km ago when I bought new tyres I had wheel alignment done, but 1500km ago I had some work done on my car, one of them being sump gasket replaced, on the workshop's invoice there was 'drop subframe to replace sump gasket'.
Do anyone know if wheel alignment must be done after the 'subframe' has been dropped?
Because my tyres was fine before I took my car in for repaires, I check them regularly.
And, it feels to me like my car is a bit all over the road after I revieved it back from the workshop 1500km ago, my wife always accused me of thinking out stuff to spend more money on my car,, but after I saw my tyres this morning, I don't think it my imagination lol.
Just a bit sad that the workshop didn't tell me I must have wheel alignment done, because basically my front tyres are messed up now within 1500km, and just 10 000km old

How long was the car stationary while the workshops did their work? RFTs could develop flat spots (which could cause the waves on the side thread you are seeing) if the car stands for too long.. Do the tyres make humming noises? Where's the tyre experts.. :fencelook:

If any portion of the suspension was loosened, the alignment must be re-checked, not saying that it will be "out" because of this, but probably.

It was about 2 months, but its not RFT's, I do the biskuit in the boot thing. I heard a story about E90 front suspention that needs to be took apart to replace sump gasket, don't know how true that is, and if that's true, I suppose alignment should be done, but nobody told me that

Yep, in order to get to the underside of the engine, lower suspension has to be removed, so alignment would have to be done. :thumbs:
