pinion depth 8.8 gone

had a housing all back braced and tubes welded ...then brought to the local guy that sets up a lot of 8.8 for racers in the area said he has never seen one this bad

pinion depth is so bad out , said a .010 ship wouldnt even go
almost like the carrier is way off and the rear end was heated up to much


Came back from vacation today to hear this
im pissed not sure what to do , now i either get another housing and start over but just paid good $ worth of work done with on housing

i have axles strangege already and spool

going to have chassis shop that did work look at the rearend and find out the cause


ANY OF YOU GUYS EVER COME ACROSS THIS ?

coilover brackets have been welded on and arb as well and yes it was done on a jig

None of that should have affected the pinion depth. Are you sure the bearing race is fully seated and or is the matching one for the pinion. I apologize if it has already been together with all of the components. I've done many 8.8s and don't see how the casting would have been affected by welding on the tubes , or for that matter to the main case itself.

^^^^^^Same. Does not add up. Run a solid crush sleeve just like the GM Boys though but, that's for pinion bearing pre-load. Are the gears new and machined correctly?

This was nothing to do with gears the issue was when using ford tool that simulates the carrier bearings .more or less the initial setup .

The issue was actually a defect in the pinion bearing ..same part number .018 difference .

It's all set now and together ...guy that sets these up never had a bearing issue from new bearings

Now I just need to get a hold of butterbean for that convertor

Used solid crush sleeves ...Richmond gears.
Everything new

Please Tell me they where not Timken? I guess everyone can have a Bad Day in the QC Department if that is what happened, or maybe it just got mixed up along the line somewhere. Glad it was an Easy Fix anyway.

It was a Timken .....same part #

I work in manufacturing , so I know first hand it can happen you just try to limit it

The height of the bearing race was the issue

Glad I'm not the only one that's run into that problem
