New Strut Rod Bushing failure!

Roadboss

On Work Release
Looks like they were installed wrong, K-8680 for rear of control arm to cross member, and K8659 for front of control arm to frame. The step should nest into the hole in the frame.

As I never changed one, he knows better than me!!!
I sometimes make assumptions that when people work on their cars, they MIGHT know what they are doing.

OCCUPY LoD :)
What if the inner sleeves were the wrong length? Tightening could have split them.

Those kinda look like the kit that I bought first too and I had to modify the length of my sleeves.

+1...forgot about that.

They were installed correctly and as far as over compressing them goes, it felt like the end caps tightened up with very minimal bushing compression. I've heard that aftermarket bushings were bad, but I didn't expect this. I did notice that the nut is brown and there seems to be a blister mark on the bushing as if heat was applied.
I never moved the nut in hopes of keeping alignment relatively close to what it was prior to new bushings. I wonder if the Lincoln dealer may have heated the nut to move it during the aligment and the resulting heat weakend the bushings? I ended up buying Ford bushings and I'm going to machine up the replacement sleeves since you cant buy them anymore individually. The endcaps are in perfect shape. You can buy a rebuild kit from Ford that includes the end caps, bushings and sleeves for $240 PER SIDE! I got the bushing for both sides for $41. I cant believe the mark up on some of this stuff.

The blister is a side effect of the bushing's manufacture...it is called thermoplastic. Whether this was any indication of defect, I don't know.

What is the best aftermarket brand these days? I remember reading that some were bad, some were improved design, etc.

MOOG are both 'bad' and 'improved design'...they corrected their own mistake.

The absolute best would be delrin, but unless DLF makes a batch, the next best thing is poly. I don't know who they are made by, but I think Bill at supercoupeperformance.com sells them. Be prepared to drop around $300 for a set though.

The blue thermoplastic MOOG bushings are a good compromise because they perform almost as well as poly, but for only $70.

I also see that Raybestos makes a 'professional grade' set for around the same price. The picture on rockauto.com looks like poly. Can anyone confirm?

That would definitely be better than paying $300 for an entire front end set.

the ford bushings are expensive but better. People have used the ones you have succesfully, but many have experienced failure. I have never seen anyone complain about the ford bushings failing except wearout. We all complain about the cost though.

The Ford rubber bushings also cause a loss in handling and steering feel...new or old.

Delrin would not be the correct material for the forward strut rod bushings, as they need to be somewhat flexible. A soft poly or hard rubber would be best IMHO.

SCP sells Poly forward bushings for $70.99.

The complete forward strut rod bushing kits can be had for just a little over $100 a set (you need 2), or if you just need the rubber bushings, without the spacers and washers, they're very cheap @ about $4.24 x 2 and $8.46 x 2.

Oh...didn't know Bill was selling partial sets now. Front AND rears are $130 (doesn't make sense to do only the frame bushings...then the control arm ones will give out) compared to $70 for thermoplastic. Not enough incentive to change out my blue ones now, but definitely a worthwhile item if I ever have to tear everything apart again.

For everyone else out there, SPEND THE EXTRA MONEY...just not on the Ford ones.
