Faulty Stabilizer bar bush, repair possible?

[k_m]

My A110 pure (with S antiroll bars) suffers from a loud rattling noise when driving over bumps, coming from the front area. Had it checked during the recent service and the Alpine mechanic is pretty sure that it is caused by a loose antrollbar bush. The right side is still okay, pictures attached.
The Alpine Center wanted to order a new bar as the car is still in the 3 year warranty, but I had to tell them that I changed them to the S version, what is not covered by the warranty, of course.
Long story short: As the bushes are glued to the bar and cannot be changed single I am afraid I need a new front bar. Or is it possible to repair/re-glue the bush with some kind of PUR glue like Sikaflex?

Are bushes glued to the bar a normal thing in OEM circles broadly, or just Alpine/Renault? Personally I've not come across that before, and have replaced many a sway bar with aftermarket versions (bushes not attached).

That might explain why some mechanics will say to only install sway bars with wheels "on the ground" so the suspension is in its normal position. So perhaps when OP's swaybar was changed that didn't happen & is why it looks twisted & torn...?

Both bonded and non bonded are normal.

I installed them above a pit with the wheels on ground. No tension on the bars this way. The picture is taken on a lift, that's why it looks bended.

Glued bushes are quite common nowadays, propably easier to equip for the car manufacturer, but not maintainance friendly for the end customer.

Have you inspected the springs for any cracks/ failures?

Yep, evetything else looks good.

Gonna install the original front bar again and will see if the noise is gone

That blows my theory. What's that leave, faulty bushings or exceeded design life? I find the latter to be unlikely, unless you'd covered 100K miles or more.

It covered just 3t km and is 1 year old. I've complained at the seller, Optimiz Access in France. They responded to file a claim by the manufacturer (afaik a German car parts company). I doubt they will cover it, but I will see...
