Center Support Bearing and U-Joints, which ones???

I'm surprised that nobody has asked this b/c I searched.

I don't think my Center Support Bearing is gone, but I have a vibration at a VERY specific speed unless I'm accelerating through it (76-78mph). The tires were rotated and road force balanced two weeks ago and all the wheel bearings are in good shape.

The rubber support is soft as in I can move it 1/2" in almost any direction and it looks like the shaft has contacted the metal bracket (not bad).

I went online shopping for bearings and u-joints last night and went to Carquest today. They sell Spicer bearings and joints. Problem is, there are too many options for both joints and bearings. I REALLY don't want to have to take the whole thing out of the truck only to haul it 25 miles to town to match parts on the bench.

There are two different bearings, only differing by 5mm id. I've yet to see a reference that tells me which one I need.

Same with the U-joints. I figured while I had the drive line out that i'd swap all three joints. There are like five different ones depending on wheel base, drive, etc. Even the Carquest guy wasn't sure.

Anyone?

ETA - sorry, thought my truck was in my sig, guess not...

'01 F350 SRW, CC 4WD, SB, Lariate
DP, ATS Exhaust, HPX, Tymar, etc....

Thanks for the info.

I just found a Spicer document that lists sizes and part numbers.

http://www2.dana.com/pdf/K350-1-DSSP.pdf

Advance lists two bearings, one that is 35mm and one that is 40mm. I figured it was the larger of the two but was not sure.

They also list one u-joint that will work in all three positions as opposed to the stores listing several for each spot.

The only 1410 bearing that Advance has is a National. It's 25.98.

Napa has the Spicer for $50, think I'll go that route

As far as your carrier bearing goes, that much play is normal. That's the way mine is too

I ran into the same issue when I did my u-joint in the middle of the rear axle. Everywhere I looked they had a ton of different u-joints for my truck. I went to AutoZone. Far and away my favorite place for parts. Everything is simple there. They asked me the same thing, basically truck model and wheel base That was it. Fit perfect and no problems I've always had great luck with Auto Zone. great parts, great tools, cheap and reliable. They always have what I need....



NO I don't work for them

Not trying to argue with you, but.... I will for just a sec.

I can see that the shaft has rubbed on the bracket..... It's not worn, but it's obviously made contact recently b/c that's the only area w/o at least a thin layer of rust. No way that is a good thing.

Well I may have missed the part where you said it was rubbing, but I just re-checked my carrier bearing again and you can move it in all directions 1/4"-3/8".
So I stick by my original statement that play in a carrier bearing is normal
I bet yours had play before your viration

Is your truck lifted? Is your carrier bearing spaced at all?
When I lifted my truck, I think I spaced my cb too much. I'm convinced that is what killed my center u-joint

Sorry for being slow on the reply. Was sick with a summer cold (SUCKED) and felt so bad that even reading a forum wasn't on my list of stuff I wanted to do.

I dropped the drive line today. Everything was easy except for the nut on the yoke. I had hit everything with PB Blaster two days ago including that nut. Impact, LONG breaker bar, torch, NOTHING would break that nut loose..... so... I had to get in there with a dremmel and cutting wheels. I finally got the b-tard off after cutting the majority of two sides and wacking it with a punch and hammer... Now I have to try to find one of those yoke nuts on Sunday at the big box auto stores..... I'm thinking tractor supply will be a good place to try as well. Any tips?

The u-joints felt generally ok. A tiny tiny tiny hair of play in one but nothing else. I replaced them and will press the new bearing on tomorrow.... once I fine that yoke nut. The bearing didn't feel happy. I won't say there was play in it, but it wasn't smooth, that's for sure. It was probably ready to go at any time.

Oh, the wife will kill me if she has to walk 25 miles to work on Monday..... ;-)

ETA, sorry, the truck is not lifted beyond the stock 4" rear axle spacer that comes under the F350 SRW.

One more thing.... I saw on Spicer's specs pdf that "u joint retaining bolts should not be reused".

????

Hope that the parts store has those as well....
