well, i got a quote from a guy here in the UK who breaks M1009's.He qouted me £250 for a diff and £150 for the spur gears and beveled gears.The complete diff swop looks the better option(less work).what do you think?

 

Don't know how much that is in US dollars, but if the whole diff is rebuilt, I'd go for that. You have a GM Corp 10 bolt front and rear (8.5" dia. ring gear),front with an open diff and the rear with a Gov-Loc differential. From what I have read about the Gov-Loc diff, they are a major weak point and many have upgraded to an aftermarket posi unit or just open if they don't need the extra traction. The problems I have read about are exactly as you have described and some have even gone through 3 diffs before switching it over to a more conventional (new tech) diff. I wouldn't be surprised if you couldn't get a newer style diff over there to swap inplace of the Gov-Loc. You would need to replace the whole carrier however. Check that out as well. Also, IIRC, you have 28-spline axles.

 

thanks for the info.

 

£250.00 is about $419 for a second hand diff.What would you recommend as a replacement after market diff.....is there anything made to replace the gogs but using the original carrier?

 

Hi,What are your thoughts on rippin out the spider gears in the carrier and replacing them with a powertrax lock-right locker??

 

The Gov-Loc carrier isn't the same as a conventional open carrier or a normal posi. The case cannot take the aftermarket posi's or lockers. If you wanted to go that route, have your mechanic find you a replacement open diff carrier and then replace the guts with the appropriate aftermarket equipment.

 

This is begining to get on my nerves....lol.The "so called tech" at summit racing reckons the powertrax fits you reckon it don't.So i won't bother with that idea.It's a long way from the UK to the USA to return something.So what do you suggest i shove in it?? Taking into account limited budget and don't want to be bashing the spanners to much.

 

GM 10-bolt 8.5" 28-spline Gov-Loc differential on eBay.com for $75 now with 3 days left. Shipping to the UK may be a killer, but it looks good. I'm not sure if it can hold a standard posi or not. I'm just going by what I have read on some 4x4 forums when searching the internet on your problem.

 

Thanks for the info,i'll have a look in a moment.Don't get me wrong i wasn't getting at you in any way.It's gettin to be a pain that's all.I think it would be easier to buy a dodo egg..lmao.
