    Default What rear axle will work on 97 2wd Suburban?

    My Suburban with 238k miles decided to drop its rear end last week. I need to find a used rear end to throw under it to get me through the winter. It's a simple 2wd c1500. Just a family mobile. I assume that the 88-98 c1500 pickup truck rear axle should be the same, but I would to confirm this. Thanks for any help. BTW, it's a 5 lug setup w/ rpo code GU6.
    Thanks, Chris

    No. Unfortunately a pickup rearend will not bolt up. The rearend has to be out of another Suburban. The width of the rearend and the mounting brackets are different.

    The differential and axle shafts are the same part # for a 97 2wd pickup and my 97 2wd suburban. Also, what brackets are different? Correct me if I'm wrong, but the only connections are brake lines, shocks, pinion shaft, and U-bolts, right?

    On the bright side there are LOTS of 97 Suburbans out there (and 96-99-maybe they fit also) .There is almost always a "bad engine bad transmission runs good when running" Suburban for sale around here-NOLA-asking maybe $1000-$1500.
    If you could spring for that much you might be able to part out the rest for most of what you paid.
    Junk yard will have rear ends- entire rear might be easiest-wheels brakes everything-just shove it under and bolt it on.

    PS 238,000 MILES-PLENTY OF MILES- did you tow or do anything that would shorten its life-maybe PO did??. Just asking because I'm wonder when this is in my future- 217,800 miles 1998 C1500- just like yours-mine the last 5 years 22,000 miles-great family 2 dog 4 cats evacuation vehicle- cost $2950 5 years ago-worth maybe $2000 now-not bad- never would sell it-can't buy anything as good for $2000! Someday I aspire to buy a 2004-maybe late 2013-pay maybe $6500 then for decent one.

    Well, I talked to the GM dealer this morning and the axle housing is the same for all c1500 body lines for 92-2000. He said the mounting is the same for the shocks and U-bolts. The axle shafts and Differential is the same part #. I'm guessing they are the same part based on this. The suburban rear axle is priced higher around here. I can get a c1500 pickup rear end for less than $100 where the suburban is $400 and way more miles on it. I bought the truck with 200k miles on it and it has a rebuilt motor and tranny. No rust on the body or frame and overall good condition of the interior. I got paid back more than I had in it from hail damage last spring, so it's a no brainer to fix it. I has the tow package, so I;m guessing p/o towed stuff. It's just a family hauler and occasional pack mule for me.

    Ok, I found the difference. Wait for it, Sway Bar brackets! That's right, pickup trucks dont have the brackets.

    Huh- yep just looked at mine-sure enough there is the antisway bar.
    If it was actually $300 less and far fewer miles-guess what I could do without!!Yeah the Suburban might sway flex a bit more- but so what- I don't really drive it that hard!!
