Re: change struts 2003 GMC Envoy XL Sign In

No telling Hammer where you know I look things up. This apparently calls them either and I would call those a strut but that info could be all wet!

Showed this......... Gabriel Ultra/Shock/Strut - Front Part Number: G51718 Warranty: Limited Lifetime
Notes: Strut must be rotated to align notch with lower control arm. Quantity per car: 2. Shock/Strut should always be replaced in pairs





Yes - inside the set up or available all ready for lots more if that type at all??

Re: change struts 2003 GMC Envoy XL Sign In

It seems like this is a name game for what you are after. If what I would call just a strut you can replace just the "shock" part inside while compressing spring which isn't all that DIY friendly or safe with junky spring re-tractors/compressor. Strong bolts at bottom would alter or could the alignment so could new "shocks" anyway if pressurized with gas (many are) the vehicle height would be altered and hence alignment.

If bouncing too much or leaking that indicates replacement needed.

I'll try to look up the # you posted to see if what I would call only a shock but bet not at the moment,

Re: change struts 2003 GMC Envoy XL Sign In

You part # thru Monroe if correct I would only call a strut........ Shown here...........



Reason that doesn't say shock is that one is whole and pre installed in spring assy. I would still be asking for a strut cartridge which does act as a shock if all this is correct,

Alldata calls them shocks. I have a 2005 but I assume it's the same procedure. Let me know if this isn't what you're looking for.

Re: change struts 2003 GMC Envoy XL Sign In

Those are great instructions but this is a 4WD and doesn't even have coil springs or struts in the front.

Re: change struts 2003 GMC Envoy XL Sign In

We have a 2005 XL XLT and is a 4WD too. That's what alldatadiy has for ours. I just kind of figured it would be the same.

Re: change struts 2003 GMC Envoy XL Sign In

That picture came from Alldata for this exact vehicle.

I just looked at a 2005 and it shows the exact same suspension.

Re: change struts 2003 GMC Envoy XL Sign In

I looked under our vehicle and it definitely has the springs. I also looked at a parts explosion on alldatadiy and it shows the same image as the one you posted. But, looking under our vehicle, it seems to match up with the replacement instructions I posted above.

Re: change struts 2003 GMC Envoy XL Sign In

Somethings all wrong with this. Either named wrong vehicle, year, 4 wheeler or not. Original poster, you have to know what you have as the two shown are approached all differently as the guys showed,

Re: change struts 2003 GMC Envoy XL Sign In

I don't know what the deal is. Something is wrong here because Alldata usually isn't.

Re: change struts 2003 GMC Envoy XL Sign In

I have no idea. If we didn't have an Envoy I wouldn't have been able to add to this thread at all. You would know well before I would. Maybe alldata just has the wrong parts explosion or left out the springs.

I'm glad I looked at this thread. From the looks of my front tires I noticed it has a negative camber. They looked fine last fall. The wife probably drilled a curb or something and didn't tell me.

Re: change struts 2003 GMC Envoy XL Sign In

No, I suspect there are different suspensions within the same year and Alldata just didn't cover one of them.

Re: change struts 2003 GMC Envoy XL Sign In

Guess we need to know which type or correct data on this thing. I dare say we've all run into conflicting data from parts outlets to whatever up to a mid year odd ball.

OP - can you send a pic?

Re: change struts 2003 GMC Envoy XL Sign In

That makes sense. There are quite a few different trim packages.

That is a diagram of an S-10 blazer or Jimmy's front suspension... someone goofed.
