Hi,
Just my 2 cents.
I have had a CP-e diff mount fitted since March 2011. I have had a Sure Juggernaught to the front of the diff as well.
For ages I've had an annoying rear suspension rattle/clunks. Thought it might have been shocks or loose mounts. It has been getting worse, accompanied with
what seems like axle tramp. I also had a hard thump from the suspension when going in & out driveways.
Finally bit the bullet & removed the entire rear sub frame, after removing the tailshaft. Oh what do I find......?
A torn front CV joint boot & a shagged rear uni-joint. The uni-joint un-repairable. Get a quote from a driveshaft joint locally, $1250 to fix. (cutting replacing shaft, installing replaceable uni-joints, new boot balance etc) A Genuine one, about $1300.
A used one from Brissy, $330 delivered, bargain.
I take a look at the diff mounts & I see this....
Then I notice that the bushes are held in with roll pins.....hmmmmm. The penny drops. Torn bushes, roll pins opposite the bolt sleeves....rattles explained, a pic of the dent/burr of the roll pin banging on the bush sleeve.
So I contact CP-e. They request pic's & an invoice proving purchase. (They advertise 'lifetime warranty') Send them the info, get a reply...."I sent these to the warranty department and I'll let you know what they say once they get back to me. It looks like it could still be cosmetic, but since the center section is pulling away, it might be covered."
They then asked me to send the mount back requesting it be warranted. To the US....
Hmmmm, there must be a better solution. Just replacing the CP-e with another suspect CP-e mount doesn't really do it for me.
So..........
My solution.
Nolathane the sucker.
I removed the CP-e bushes.
Which explained the use of the roll pins. A thin metal sheath around the bush material. Most bushes I've seen have a solid steel surround that requires a hydraulic press to fit them.
I then knock up a mandrel & chuck the bush sleeves in my metal lathe. I cleaned up the OD surface removing the CP-e bush material.
I purchased a 75mm x 300mm solid bar of Nolathane 85 duro urethane from Repco, arrived overnight, wow!!! I expected a week.
JFT I had to modify my lathe to accept the 75mm bar. The steady rest was too narrow, FFS.
Measured the CP-e mount & turned a 4 piece set of bushes using the original bush sleeves.
Problem solved, I believe permanently. Warranty, I guess now void. BUT, I don't have to pay for postage to the US, wait for CP-e to look at the mount, decide whether it is 'cosmetic' & then send me a replacement mount (over Xmas & the New Year), manufactured just the same as the one that failed.
A satisfying endeavour nutting out a solution to a failure, & then making the items myself to fix the issue.
