Hi guys,
Just found my left axle seal weeping some oil (pinion seal has been seeping since i replaced it in subfreezing temps 3 or so years ago)
and my g80 is starting to act somewhat funny, although this may be my imagination.
along with that, the dust shields are gone and the leading caliper placement of the blazers cause pretty fast pad wear.
So, brainstorming why i should or shouldnt replace it with a pickup axle.
internally they are the same as far as i know.
the things I believe are different
1. bumpstop pad location
2. caliper location
bumpstop pad location isn't a big deal, I can add whatever wherever later.
caliper location seems like it wouldn't be a big deal, but i don't understand why GM placed the calipers on opposing sides between the SUV/pickups.
in general, for offroad usage, leading caliper placement causes issues with rocks/crap not falling out as you drive.
I've noticed extremely fast rear pad wear most likely due to this.
I don't see anything on the blazer specifically (im only looking at a zr2) which requires the use of the caliper in front of the axle.
anyone have any insight as to why GM would bother changing it up?
