I never changed my mounts all i did was chassis swap a suburban with a avalanche. Which btw uses same mounts.What were the PN for the body mount bushings you used?
I'm gathering parts for a rebuild of my 2004 Suburban 2500 LT . This will include replacing all the rubber isolators. I don't want to use polyurethane but if that's what you used the PN might help me.
Fof anyone else doing this, this is what I found online so far:
The online OEM part finders list 15837581 for the upper radiator support bushing and 15201791 for the lower bushing (rubber cup); however, the description says that for 4WD, 15837581 goes in positions 1, 3, 4, and 6. It also shows application up to 2014 Escalades. Of course this does not match the sketch which shows this goes only in position 1 (radiator support) and that 15201142 goes in the other 4 positions; but wait - there are 5 other positions (12 body mounts for suburban counting radiator support bushing). So, the picture must be wrong!
Enter Dorman 924-040. When you search for body mounts for this Suburban, the Dorman 924-040 and 924-138 come up. The 138 is unavailable (more on that later) excep for a few websites which sell it for way cheaper than the ones that list it as out of stock. These websites are probably bogus so don't buy it from them or you can kiss your money goodbye. For 924-040, some descriptions list it for positions 1 and 4 but this doesn't jive with the OEM websites - unless you assume Dorman does not count the radiator support as position 1. With that assumption, Dorman position 1 and 4 become OEM position 2 and 5, whicb works perfectly with the 15837581 OEM description saying it goes in positions 1,3,4,6.
But where to get 15837581? I found Dorman 924-133 on Rock Auto with it showing that the OEM PN for it are 15837581 and 15201142. So I bought some, along with some 924-040, which measure about 1/8 of an inch taller than 924-133.
So, now what? I would hate to be torn into my Suburban only to find that I have the wrong mounts. Also, the plan was to do this last in the rebuild sequence so I could install a body lift if needed to clear the 37's I plan to install.
Bottom line is I'm looking for definitive, current PN info on body mount bushings for my 4WD 2004 Suburban 2500 LT.
Sorry but thats as far as i went with mounts
