    Today I reversed and it went clunk.. clunk and now is making a gawd awefull I am dying sound:crazy:

    the suburban is a 3/4 ton and with 130,000 on her. I am wondering if the perches are the same as the older 14 bolts? or if they changed? ??

    I figure it will be quicker to swap a rear and cheaper, most yards are 150.00 on up for a full floater and that should save me some time and money when you factor..

    new ring and pinion
    bearings
    and install cost.. :eek1:




    any idears?

    Perches changed for 88+ IFS, so I can only assume that the newerfangled ones are different as well.

    located a 27 spline t-case just a few miles from home for 100 bucks:bow:

    now i just need to pull the two cases apart and swap in my 32 spline inpute shft into the donor case:doah: :eek1:

    just looking at these torsion bars freaks me out about this swap..and complicates the whole thing

    Fyi... Suburbans didn't change until '92 (not that it matters for this case).

    is anyone real knowegeable on these 241's?


    I am hearing a million different things on this, also it is sounding very complicated from what I hear to drop the torsion arms? Am I overlooking something or?


    this is my daily driver and its already killing me work wise with my truck down,

    the t-case I found for 100.00 turned out to be cracked :(, and most people want 500.00 plus for the t-case alone! I am temped to just have a shop do this but then I am looking at some serious $$$ that just aint there.

    any ideas?


    this sucks, sometimes trying to make it with your own business sucks, I could just temp fate and keep driving but then when the grinding stops and it grenades I will be left with a towing bill too:(
