AAM driveline Center Support Bearing Insp

[GCroyle]

JR,

Yeah rust belt ruined my 1968 Olds Delmont 88 rag top and my 1st handshaker a 1975 Camaro 350 4BBL.


OK it's down time waiting for a new CSB after I ruined the install of the new one.

Used a nearly miniature HF bearing splitter and got the old one off after it resisted first efforts to get it off with the hand operated inertia tool and punch. I made a tool similar to the FSM driver a 9" X 1 1/2" iron pipe with the threads filed off to clear the shield around the bearing. Tapped on bottomed on shaft and oh yeah!

Until I tried to turn the new CSB. Rotated THUNK and repeat. Look for the red oval. My punch made a divot in the slinger! that I failed to fix prior to new CSB and that divot kissed the new CSB dust shield. No chance for recovery IMHO and truck isn't needed right no so order one more CSB. Kick butt, get on with it.

That slowed the pace back down in the shop and I cleaned up the divot in the slinger and then pondered how by myself I would hold that heavy engine end of the slip yoke with its steel damper and fit the joint and then marry it to the shaft.

Two pieces of scrap 2X4 and a 2X10 for the base. The slip yoke end went into a round hole in the 2X4 and shaft riding on a smooth surface. The CSB end sits in a semi circle rest. Now it was rotate to position, install joint, rotate etc then flip it around and marry it to the shaft.

You might think it unnecessary but it really helped hold clumsy parts and let me focus on the cups and cross detailing.

Hope the storm don't mess up my new CSB shipment but that's the snow around western NY area where it's coming from.

Maybe too late to the game for my $0.02,, but my CCB looked exactly the same as you all have and was replaced along with the weighted front sliding yoke on the trans side. DL was balanced and all U joints replaced, still had VIB around 70~73mph.... When I picked her up it was still bad / no change so I pulled front DS and whalla.... no VIB. Turned out to be the front drive line! Rebuilt the front with new ujoints and balanced, been good for 6years.. Gald all the rear DS work was covered by extended warranty,

bcbender,

I can rule your fix out for my truck, mine is a 2WD

The new CSB arrived and today is scheduled for final assembly.

Stay sorta tuned.

ya.. that would change things... sorry I didn't see it was not 4WD.

maybe it'll help someone else down the line.. I swore that my seat judgement was main driveline

I think you'll be good to go with an AAM support bearing. I went thru 2 Napa brand ones in 80,000 miles (for more money too). When I took the 2 piece shaft off my truck to put on my 1 piece driveshaft, the AAM center bearing rubber looked brand new.

I got a whole new respect for this mundane R&R task.

First local test drives completed under my own power.

Kinda proud that it included a minimum amount of hammer time.

Need to get some highway time on it to see where I am on the original Customer States issue.
