C'mon everyone: Bring on the breakage stories- Has anyone ever broken a sierra spindle? any size tyre, any abuse. I have a little project on the go that looks like it might require the ID of the spindle to be opened up to 30mm instead of the stock 29.2mm. I want to know if I'm likely to break spindles after this is done. I know it is done with D60 rears etc to go to 35 spline axles etc.
I will be running Q78 swampers and the rims are approx 3.5" backspaced 7" beadlocks. I know (or anticipate) that bearing repacks and retentions will be frequent etcetcetc.

Sierra spindle strength

This doesn't look like it will be a problem anymore - I have reviewed the way I am sorting this out and will not need to bore out the spindle.
Running stronger diffs will not be an issue, when complete, I should have plenty of diff strength, however, there will be a reasonable amount of load on the bearings and housings. I will need to strengthen them I suspect, along with the transition from axle tube to swivel.
Many aspects of the build are still up in the air @ the moment. Once, they are sorted out, I will probably start a thread here.
Current "fixed" components are:
1986 LWB chassis, un bobbed.
RUF, rear 3/4, rear sierra OME packs.
welded rear, Lock right front. 3.7 WT centres
1.6 bottom end into trimatc into vit t/case into series 1 'hopper.
15X7 beadlocked rims with urethaned inner beads and Q78 swampers.
Other stuff being worked on will include Full foating axle rear and front hubs all 'round so four wheel discs too.
I do not consider the G axles to be that much of an advantage. They have a unique front wheelbearing design that is a PITA to rebuild, the rear is semi floating, and the front runs back to front. (It is literally a rear diff upside down) ratio is 4.88, so nothing great there, and the lockers, being hydraulic, require a fair bit of work to set up.
I am trying to build a car with as many Zuk parts as possible, and the requirement for an offset rear diff would limit me to MQ or LC diffs, that have a diameter that eats up plenty of clearance. To my mind, tghere is little point running a 35" tyre on a Nissan diff if you can run a 34" tyre on a sierra diff without too much breakage.
As to running a 35.5" tyre spua on narrow track diffs with 3.7 centres... well I'll just have to wait and see if what I am planning works... then you'll all be the first to know.

Not a chance. I'm taking my time - It hasn't run for years, so there's no point rushing it to get it going. I am trying to do the whole build at once, as the body is off the chassis etc, I have a chance to do everything as easily as possible. Basically, I also have to redo all the work that I dod iver the years, as this was compromised by a) not having a complete vision for what I wanted the car to do B) not having the skills or tools I have now, and c) having the body on the chassis.
None of those things apply anymore.
Oh, Pete and Bigsteve :
