guess I wasnt clear, this is an 8.5 10 bolt not a 12 bolt. JD has been super in communication, sent him even more photos than here to try to show as much ss could. guess we will see next week what moser does or doesn't do.
I think 8.5 and 12bolts have the same bearing ID on the carriers, may be wrong tho,...to be honest a Buick 8.5 has more robust looking center section than a 12bolt,..the bottom main cap boss is kinda hung out in thin air with the 12bolts
I love my 8.5, but this is truely a no win situation for me. if they replace these axle I would in 20 passes they look the same. no good. if the step up and go above and upgrade to 33s, now its 200 for new spool, 50 for carrier bearing, 100 for housing ends, 100 for axle bearing, plus labotmr to have the end put on.......200-250. I'm not going to put another 700 in my 8.5. I put almost a 1000 in it 20 passes ago with spool, bearings, axles, ta cover, arp studs etc, to do it right I have my concerns on the spool with 33 spline axles......that extra thickness in the axles means my spool is that much thinner. do I fix my axle issue to make a spool issue. I very well might have a 8.5, 30 spline, full spool, with 4.10 gears and ta cover for sale soon. that and my 700 gets me close to full prepped 9" I'm stuck, not being able to go ahead with my brakes cause I dont want weld on my brackets just to sell it, now the tab brackets are cheap, but in the off chance I do go 33 will they be in the correct spot. I have just about 30days till the first race I wanted to go too.......its not looking great seeing I have no brakes, no axles.....well I can run what I have I guess, engine and trans together sitting waiting,
one thing I did learn today was they use the same blanks for 28,30,31 axles. they just turn them down in diameter then cut the splines. so is this done b4 or after they harden them. if they are treated first then cut, they cut off some of the hardened part
Are you running transbrake? Gotta be harder on axles.... I ran mid 10s at 3770lbs with 28 spline stock axles with spool in 8.5. High 1.40 60ft. Kept twisting driver side....my low tech solution was to NOT screw slicks to rim. Then on a hard hit tire would move a little bit on rim rather than the axle taking all the hit. Kinda like a cushion. 50 passes and it moved about an inch. Don't laugh...worked for me....
I'm running tubes in my tires so any turning there will hurt the tube. we are on a brake, but about 3000, about half those passes of the 20 were what I wil call shake down passes, lighter foot brake, lower rpm shifts, just slowly stepping things up, and braking parts in.
moser basiclly said kick rocks, they warranty their 33 and higher splines for 10 years........but you have to break them first not just twist them.......so you have to ruin your rear axle and possible wreck your car then you have warranty.......sounds alot better than fixing b4 it's a problem. so I guess I see how long they live?
I wonder how many passes they are good for? I have 33s in my 12 bolt with 600+ passes. Maybe I should pull them and look at the splines.... I should have painted a white line on them......
I think my weight is the biggest issue, for 1000ish I can get 33s in my 8.5, but the last thing I want to do is drop that again and find out I'm still having issue. I think the best thing for now is to get off the transbrake when I race to help it out some till I get the funds to get a 9" with good parts and 35 spline. going to put together another housing I have here with 28 spline spool and gears I have just sitting and see if I cant get a chunk of the funds needed.
if they are twisted you will be able to tell, mine are not bad and I knew when I had to take a slide hammer to get them out something wasnt right. just to completely verify on mine im going to pull the spool and see if they engage any better.........I tried putting the axle in without the outer race on the bearing so the axle wouldnt have to be centered no change......I was checking for bent tube
I want to say a special thank to monzaz for helping me try to work through this with moser. I ve still been talking with them and might be close to a solution. but it's clear a rear setup that can handle is what I need, so this 8.5 will be coming up for sale soon.
Ben I don't know if this would work for you but if it could you might save a pile of money! Of course, you could also spend a pile getting a narrowed rear set up in your drag car... Just an idea for you. http://www.v8buick.com/index.php?threads/ford-9-package-w-axles-spool-wheelie-bars.344507/
well my brain wouldnt stop so I puked everything part down to bare housing here to check everything top to bottom. with the spool not in the housing I can slide both axles, down each side of the spool all the way till the splines stop with no issues what so ever. so looks like even though the spline dont look straight by eye they are not binding in the spool. housing????? going to put just the spool back in and see what they do, I also have my 28 spool sitting here ready to assemble for another board member maybe I will set in just to see how the factory axles go in and out. if both are tight it has to be the housing
so I put the spool alone back in with the same shims removed, minus 1 .010 side shim. for the life of me I just couldn't get the shim pack to start. it still had tension to the back and no measurable end play, axles slide in easier, I tightened both sides down. axles and spool turn smooth as butter. went to pull axles both sides just pulled right out as would be expected. no slide hammer needed.......so I dont think my housing is bent........it had to be either gear alinement or too much preload putting everything in bind. guess I continue on with my new gear install and go from there
back in the early 70's when they came out with cement starting line and tracks, the carnage was pretty good because it something totally new and different. when we were at summer nationals at Englishtown, it was something to see axles breaks, camaro rears turn in circles and other issues. watched a duster bang 2nd gear and poof, up went the dash. guess he blew a lot of clutch and whatever. took 2 hooks, front and back to take him off the track. fred's 70 c/sa twisted the axles all the time and after a while the body around the side window was moving. so expect any non performance axle to twist.
well I couldnt under stand how it could happen with my particular rear end setup on bending an axle tube. I can see how the stk set up can. with the lower arms mounted lower than the tube and acting almost like a pivot point and the pinion wanting to walk around the ring gear and up. The alf weibe set up is slightly different.....it has another bar that hooks to the bracket for the pinion snubbed and then heading down to the lower arm where it hooks to like a bracket........making a ladder bar setup......but with the second bar the top of the tube cant go back a d to bend the tube I would also have to either stretch bot bars or the lower arm mounting bracket which has triangle gussets to the frame and bars to the upper mounting locations as braces. the top control arms are basically used to only center the housing and carry 0 load other than side to side forces.....the actually hook to a cage loop that goes to upper ears with spherical bushing so with the himes and specials there is articulation in ever possible direction as the housing travels vertically on launches or bumps but never impedes its motions. only controlling side to side forces. the factory upper setup has to deal with side to side but because it only has the single pivot up top will effect pinion angle as it travels vertically
