Hey everyone,

Given that MNC2370AC is pretty difficult to find for the front subframe, I've reached out to Polybush to see if they had any ability to make a replacement. While I'm going through the process, I just wanted to see if there was anyone else that had interest for a pair of them.

Looks like they would need to sell around 100 bushes to get off the ground due to cost.

Hey Highhorse,

Those are all the same URO manufactured aftermarket part that are typically undersized:

Unless you’re making a race car out of it, I’d stay as far away from polyurethane bushings as much as possible. Single worst mistake I made on my GN about 20 years ago. I know that we're currently very limited on quality parts. If I was in your situation, I’d get the undersized URO bushings. When you get the old ones out, I’d remove the old rubber and reuse the old lead (??) casing around the new URO bushings to make up the slop. Unless your bushings are absolutely destroyed, I’d maybe lower the subframe enough to install some rubber inserts to stiffen/support the existing one until URO has these available at the end of 2026.

 

Agree: On my first X308, in 2002, the dealer tech switched out the bushings with poly: rode like a jacked up Ford p/u . . .

 

I was unaware these came undersized, ...but it wasn't specified. This is something I may have to do in the near future, so an FMI to me.

 

I will echo Addicted2boost and Jhartz...

I had a indie change OE to poly bushings on an '87 V12 VDP and while I wouldn't say the ride went to $h!t, it was noticeably less compliant/comfortable with little or no commensurate increase in handling albeit that is a non-track tested conclusion.

I still miss that car as much I enjoy/enjoyed both of my 92's. It was always what I call "a happy car" that seemed to want to be driven and not just a "car that you want to drive" if that makes sense.

 

Google shows quite a few rubber ones available, but they’re a little pricey. I replaced mine several years ago. At that time, they were still available from Jaguar which is what I suggest if you can find them. I generally don’t like poly bushings because of the harsh ride, so I suggest going with rubber, even if they’re not OEM. Just my $.02.

 

Another thought for polybushes, although less relevant to a road car.

Years ago I used them on a LR as people said they were great etc etc, then drove in sandy places & they wore out in no time.

 

I replaced the bushes on my car and fixed them in place with Loctite 638. Have put a few hundred miles on the car without issue
