What is this, and why is it on the floor?? ( '05 Yukon)

[mountie]

Drove home yesterday and parked in my garage. This morning, I see this on the floor ( under left side ).....
I would appreciate any helpful hints. Then I'll do some maintenance to replace these little 'turds' ??

Looks like a bump stop

Easily replaceable, it sits/snaps into the cup-like mount. You should do both sides

Thanks.... Good to read it is easily replaceable..... ( What sort of junk did GM use, to make these things ?? It feels like a styrophome )

I find different prices for the rears ( $13, reg autoparts.. - $25 each Summit )....
Is a "Bell Tech" version better , or is 'standard' OK ?)

Kind of confusing to where to buy..... ( I see 'square' for the front, but that looks incorrect?)

15153958 is for RWD front jounce bumpers.

These are my fronts off my 2004 in 2017: (I'm in Texas with extreme heat)

That messed up hockey puck has been eaten up from corrosion. Has this rig spent time in a salt on the road state? How close to ocean salt air do you live? Check all you body mounts too.

The most important ones are for the front, since they are part of the suspension and (should) contact the lower control arms.

Did you lose the fronts, or the rears?

To be clear, the fronts are jounce stops and the rears are bump stops.

See this link for an explanation:

Front Bump Stop Issue

Previous owner hacked off the front bump stop cups and I am having a helluva time find some sort of replacement to bolt In. Truck is an 01 Tahoe with belltech drop spindles, Purple Keys and Stock replacement shocks. The front end bounces really bad and sways when going over bumps and dips...

Lost the rear.....
But I will replace all

Not to be nit-picky, but isn’t the spec touching, or within 1/4” or something? Pretty sure mine are just about 3/16” away, while sitting level. Hoping that’s ok, or I’ll have to get slightly larger spacers.. (these pics are while in the air)

You'd better fix that...

Seriously, though, I'm not sure of the spec. All I know is that they contact on stock suspensions.

In your photo, it shows a red lower pad... Mine is just the metal surface, ( with the upper stop against it)

I added those to make up the difference, after leveling the front.

Did you raise the front on yours, to need the extra 'bump' ?

Yes, just cranked the torsion keys, and installed 2” longer Bilsteins. She rides great! May also help that there’s a fat Hellwig sway bar up there..

if I still lived in Kalifornia, I would be driving on hilly & twisty roads. But, here in S. Florida, the only 'hill' is a freeway overpass. So, my '05 seems fine.
Years ago, I had a 1970 GTO, bought in '73..... I had the suspension modified and it handled almost like a Trans Am race car.
This Yukon is sort of a 'beast'..... But it seems fine....
