Audi A4/S4 Front Upper Control Arms Replacement - The Damn Pinch Bolt!!

- Опубликовано: 18 янв 2022
- If you have an Audi A4, A5, Q5 or some VW Passat's and other VAG group cars, you might just have this style of 4 link front suspension. While the handling characteristics of this setup are pretty good, the wear and repairability, well, not so much. I need to replace the two upper arms on both sides of my S4’s suspension. It has started to have small tracking issues, and inconsistent tracking too. On one road it will pull very gently left, and another it might pull slightly right. It also tram-lines quite hard now, where bumps and grooves in the road pull the car in their direction rather than the car staying on it’s own course. And a visual inspection reveals a fair bit of cracking and play in those bushings.

Spent 20hrs knocking and drilling both sides on my avant wish seen this before there was a 1cm of bolt left for both sides and now I have a saloon and guess what want to lower it and need to change the arms aswel oh the joys such great bit of engineering 😢
Well spoken and great job. This has been very helpful.
I can thoroughly understand every bit of your description and would have my first attempt on the pin bolt section.
I only came for the "äl-you-min-yum", but I may now finally get over my procrastination and get on with installing the SPC adjustables (that have sat on the shelf for months) in my 2010 Avant. Great work!
I recently did this to my 2012 A7. The best method I found was to take the nut off, and spray it for days before frequently with plus gas. On the day of reckoning, I used plumbers gas to heat the bolt and ally up. A welder told me that aluminium will not be affected, by the heat of one these torches, as they won’t heat it to melting point.
Thanks for uploading👌🏾

Try cutting the head of the bolt off and then remove the nut from the other end and put a couple of washers on the bolt. Replace the nut and tighten. This will normally draw the bolt out. Plenty of lube though. Good luck. 🚘
My pitch bolts were a pain in the butt the first time I took them out. When I reinstalled them I slathered them in anti seize and now they are easy to get out. I had to change my upper control arms about every 30,000 miles. I am lowered 3 inches in the front and they don’t like that
Apply Duralac to your new bolts its made for the job.
Hello ✋🏻, i need your advise please. My ride is Audi A4 2006 2.0L ... I had a complete set of control arms replaced today (total 10pcs), and being aligned afterwards, but unfortunately i experienced a very stiff steering wheel. Any clue ?
Do you have a link for the parts
Mine are super easy to replace. Southern California weather. Zero salt. Come right out. I change them every 30k religiously
What was the mileage at the time of the change?
Did it make any noise while driving? My one is making a knocking noise while driving slow and braking, and when I'm doing 70mph and brake slowly I have a bit of vibration in the steering wheel.
How is the correct ride height measured?
I once scrapped a 2002 A4 due to spending 2 solid days trying to get these bolts out.
Nice job! Where did you get the MEYLE kit from? I've looked on ebay but can only find sellers in Germany for it? Thanks
Is this for b9?
It is my understanding that you should not heat aluminium as it makes it become brittle.
