Perhaps a moderator will move this thread from "Transfer Cases" to "Axles + Brakes".I’m pretty sure this is in the wrong place, hopefully someone can fix it.
Folks don't believe me when I say the "10-bolt" is a fragile piece of crap when installed in a full-size truck.I have a 98 k1500 Silverado. I grenaded the rear 10 bolt differential.
Common upgrade which probably also got rid of your crappy 254mm leading/trailing shoe rear drum brakes.My uncle has a 94 z71 that he is parting out so I took his rear differential. It is a 14 bolt, it bolted right in I just had to have a u joint sized.
(I know the gearing is different)... ...will that differential be a direct swap?
Which gear ratio is the truck set up for, and what gear ratio is it going to receive?The gear ratios are different
I was asking about the 94 donor truck, but thank you though!You have a '98. It's a 4L60E.
If you're not in 4WD, so the gear ratio difference makes no difference.
My 93 does.. and I drove around for years with mismatched front and rear diffs..didn't use 4wd obviouslyKinda thinking the '94 also has a 4L60E. Not certain
Could also possible be a throttle position sensor, mine wouldn't want to go into a 2nd or 3rd gear randomly, although I never had a random downshift, replacing that sensor fixed it for me.So I got the front differential from the 94 z71 I was talking about ( I got the rear dif from the same truck) I was driving home from getting it ( I was in 2 hi thinking it would be ok even though the gearing is different) I was doing about 25 maybe 30 and the truck acted as if it downshifted, so I pulled over and started going from a dead stop and when it shifted into 2nd it did the same thing, and didn’t want to go (almost as if the trans is slipping, kinda reminded me of when I popped the 10 bolt) so I dropped it into first and shifted it manually and it seemed fine for the next couple blocks till I got home, so I don’t know if it’s something with the computer, trans going out or something with the tansfer case/ computer because of the different gearing? Even though I was in 2hi. I know the front differential doesn’t totally disconnect like older truck where you have to get out to lock the hubs, so maybe it was binding? I don’t really know. I’m gonna swap the front dif tomorrow if it isn’t raining. On a different note, like I said the donor truck is a 94 z71 1500. I believe the trans is a 700r4 because it has a torque converter cover on the bottom of the bell housing like a th350 or something. But I didn’t really look to make sure it’s not a 4l60e, if it winds up that my transmission is going out. What goes into swapping to a 700r4 if that’s even what it is. Figuring out tv cable and what else? I hope that wasn’t too confusing for yall
