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

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

Interesting that works so well for you. I have no experience with those shocks. I live by a quarry so all the heavy trucks are hell on the roads. There is not too many options to avoid bad parts. In my experience a lot of people with poor ride quality on these trucks assume that the front...

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)
