What did you do for your ZHP/BMW today?

[M3TA5IN]

I have V12s and ver very slightly drift to the left, but also know I need an alignment.

[UdubBadger]

i have the slightest vibration in the steering wheel at ~60mph, and a steady pull to the left at all speeds. just had alignment done. the shop said they noticed some "radial play" ie, tire wear, that could be causing the pull, but the tires don't even have 5k miles on them. hankook v12s. wondering if it's something else to do with the suspension, or maybe i need the "roadforce balancing" after my new wheels??

Same thing and I know it's not my Conti's. I really think its suspension related.

I was just gonna post asking about suspension parts, looks like I timed it right!
Dane, few questions, on a rough road I get a thunk from the drivers side from wheel well when going over real rough ground. I'm think sway bar end links, but I'm uneducated in this.
Also I KNOW iv read what bushings need to be replaced when I occasionally get a slight jerk of the wheel when I press the brakes.
I'm saving up for a suspension refresh so I'm making a list now, planning on a sport cup kit, would like to do it right without spending a ton of money.

A thud sound when going over bumps could also be wheel bearings. Easiest way to check those is to jack up the car, and then grab the wheel at the 3 and 9 o'clock positions... Try to wobble it side to side. If you get a lot of play, wheel bearings are most likely shot...

Typically thud could be severally worn CAB's or endlinks. Wheel bearing would have to be FUBAR to make a "thud". Wheel bearing wear is typically characterized by a whooshing sound.....like a sandy bearing.

so after googling, it seems the Hankook V12s are notorious for tire pull to left. corroboration:

now, there you have lexus, BMW and Mitsu owners all saying the same thing. i'm thinking maybe it is tire wear after all...

Dane, might you be a gentleman and link me to some good diy's for both those parts? Many thanks

My car pulls to whichever direction it feels like. Somedays it pulls to the left and other days to the right, and other days it drives perfectly straight. I blame tramlining as the alignment shop took a look at it 2x and they stated everything was good.

Edit: I don't have the Hancook's. I have the OEM Pilot Sports.

Today I picked up a new rain sensor plastic surround cover (for future project), a new GUIBO w/ bolts and nuts for the ZHP.

I'm planning to install the new GUIBO with bolts/nuts when I install my SSK at Chad's house...

This is what I've noticed over the years...
I had two sets of Hankooks on my ZHP and Kpro had a set on her 325 we didn't have any issues other than when my tires started getting worn, I got some noise and tramlining. I did note that when I swapped them out that the front left inner tread was worn more than the right.
Also, since my tires are staggard setup and the Hankooks are a directional tire, the tires can't be rotated... that can kill one tire while the rest are ok...

When I put the Dunlops on my car, it tramlines like a mofo

When I had Bridgestones on it the front left tire started chopping. After I swapped out the shocks, it went away

I have noticed on high performance street tires, be it Bridgestone, Dunlop, Hankook or even the Michelins on the X5, they all seem to get noisy and tranline bad once the tread starts wearing out

Sounds right. I have a staggered set up and the tires can't be rotated. The inside of the front tires are wearing faster than the outside. I bought the car with 58k, I replaced the FCAB's and rear tires at 72k. I am at 79k now; so 21k+ miles on the front tires (car had them already when I bought them).

It is pretty bad on imperfect roads (almost all roads) to the point it feels like someone grabs the wheel and turns it. I'm cheap so I'm waiting for them to wear some more. They are noisy as hell between 25 and 45mph.

just jacked the car up, front drivers side was not moving anywhere with a 3/9 oclock push-pull or a 12/6 oclock for that matter. Passenger side I could push in and out a tiny bit though. I assume this is where my steering wheel play is coming from at high speeds?

Sound like a tie rod adjustment/replacement needed or is it most likely my CAB failing?
