How long do suspension bushings last?
I was tossing around the idea of a FULL suspension refresh on my 2006 4.8is while I have a seized tie rod end. However, the control arms, thrust arms, and front ball joints were replaced with genuine BMW parts just 25k miles ago (4yrs ago). I'm wondering if I should perhaps omit those two items from the refresh. I've only towed once in that time (400mi) and this truck probably sees below average harshness of driving conditions/behavior. Can anyone offer insight into expected lifetime of these suspension components:
Front Lower control arms (wishbones) Rear Upper control arms Tension Struts (thrust arms) Rear Ball Joints Front Ball Joints Rear Integral Links Upper Guide Links Here is the collection of parts I am looking at: https://www.fcpeuro.com/products/bmw...e53-x520piecel Any feedback (even ballpark #'s) is GREATLY appreciated! Thank you! |
Depends greatly on the driving habits and how many pot holes you hit.
My lower arms wore to the point of giving me steering wheel shake so I bought new arms and before I found the time to install them my wife's replacement arms wore out and I had to put them in her car and get another set for me. If you aren't getting any negative feedback from the 25k parts I wouldn't preemptively replace unless the kit price saves enough to make it worth it. |

Also, I didn't consider that my wife's '04 3.0i has not needed any of these items replaced in 50k+ miles so that could help my perspective |
Anyone else have other feedback before I purchase parts list?
Thanks.

ajacks8 - a thought on those tie rod ends, had a set seized up on me on a buddies mustang way back in the day, same scenario, seized to the point they couldn’t align it and wanted to do both inners and outers for an astronomical price obviously.... $6 and a can of “pbblast” later, those tie rods ends were no longer seized and he was fully able to align the car.
Craziest part, he took it back to the same Firestone and they didn’t say a word about it [emoji106] EDIT: when they put it back together, ask them to put a very light coat of anti-seize on them. Sent from my iPhone using Xoutpost.com |

Heck, if it burns your hands less than the pbblast, you may have turned me on to something new [emoji106] I’ve not seen it local but I’m sure it’s easy enough to find online, may have to give it a go. Sent from my iPhone using Xoutpost.com |
I just replaced the front tension arms and wishbones and the rear tension arms and wishbones and integral links and the connected bushing/ball joint. My car had 60K miles and was almost certainly on all original parts.
Only replacing the front tension struts made a difference; everything else appeared to be quite serviceable and the alignment at the back barely changed. |

Thanks for the insight, ts! Sounds like I should probably go for all of it while I’m after it. Sent from my iPhone using Xoutpost.com |
