looks to be a rubber gourmet of some sort... i tried looking up online but could not find a part number... my right side fell out due to the hardening of the rubber... guess its time for me to replace them

anyone could help me get a part number or pt to me where to get it.. i am thinking some other GM trucks uses them

thanks again

 

I'm fairly certain that is the bottom body mount. The upper and lowers are sold separately I believe (trying to remember what the dealer told me).

I'll see if I can dig up a part number.

 

That is a lower insulator and it should have a steel disc with a center hole bonded to it.
If one of those are bad then I'll bet that all 12 are bad.

GMPartshouse has them at $12.88 each

yup that looks right... i was looking about online for a week ...

thanks this helps... guess time for me to check the other 10 pcs.. i am very sure the front 2 are gone..

 

just checked them and yes they need to be replaced... one fell out when i shoke it to check how it was ...

how difficult is it to change it oneself?

 

Very easy. No need to jack up anything.
Just remove the bolt, toss the old insulator and replace with the new one.
Tighten bolt back up.
Times 12.

Should take less than an hour to do everything.

 

Questions: How do I know if they are bad? Should the upper one be changes? Who wants to come to Colorado to help me :-)?

 

noted.. i pray the bolts dun break off as it seems rusted...

 

i think i will trash the bolt... is there anyway to find the bolt size?... i cant seem to find any info on this bolt ... except its a M10 bolt x 1.5 pitch ... not sure of the length... i know the front and shorter than the rear...

anyone has a clue?

 

Man1 - the upper mounts are solid rubber. They aren't going to go bad for a very long time. The lower isolators are a thin walled rubber donut with a steel disc bonded to it. The rubber is usually fine, it's the steel part that rusts and detaches from the rubber.

eleewhm - All of the bolts are the same length, should be no need to trash the old bolt either, they are galvanized grade 10.9 and should be fine once you get them out. They are Flange Bolts and have a special rounded tip that helps to line everything up as you put it back in. They are also almost completely threaded the entire length. (an important detail)

If you really want to get new bolts, I don't think 10mm is right, they are bigger like 12mm-1.75 and are about 5" long (whatever the metric equiv. is, 120mm?) They need to be 10.9 grade (grade 8 might be OK). Make sure they are threaded far enough too, most standard bolts are only threaded about 1-1/2" from the tip. You need at least 2" of thread. Be prepared to pay close to $10 per bolt if you can find them.

Your choice but I would reuse the old ones.
