i was replacing my lower ball joints for the 2nd time in 2 yrs, this time i went with Moog. i noticed this rubber bushing thats mounted on the under side of the upper control arm. the rubber has degraded pretty bad and is crumbling. i want to replace this but i dont know what it is. can somebody tell me what its called? also are they easy to replace? it looks like a simple unbolt, but i have been known to bite off more then i can chew. thanks

 

Moog makes two different ball joints. Type "R" is a lower quality replacement that you may be changing again in another 2 years. The "problem solver" comes with a grease fitting and lasts much longer.

I believe the part you're describing is called a control arm bump stop. Easy 1 nut replacement.

 

Available at a GM dealer, GM Parts direct, Rock auto, etc. GM part #15590236 (well under $20 each)

 

i got the Moog K5335 Problem Solver that had the integrated boot and grease fitting

any links to where i can buy the bump stops?

 

sorry Captain Hook i didnt see you post when i replied (3 am lol) any way the part number you gave me does not look like the part i need to replace according to pictures. here is a video of a guy replacing his ball joints (if its somebody here i apologize). if you skip to 7:00 in the video he puts the camera at a direct shot of the part on my Bravada that i need to replace. any suggestions?

 

so i have done a little research and found a part number on the old ones 15956547 and found the replacements from Dorman
Dorman HELP 31064 - Control Arm Bumper | O'Reilly Auto Parts
but how do these come out? i dont see a nut on top but then again all this is under the control arm so if there is a nut, its virtually impossible to get to unless i remove the control arm (like i said bite more off)

 

I think that's the lower control arm bump stop in the video at 7 minutes. This might get the "thumbnail" from the 7 minute mark, or at least link to it.

GM part # 15956547. Dorman makes an aftermarket version, Dorman # 31064.

 

do you know how to remove it?

 

Looking at the pictures of the Dorman version online, I'd say there's a nut above it on the threaded stud from the part.

I guess you have to get a wrench into the frame rail channel to get to the nut. The part looks like it has a locating "dowel tab" on it, probably to keep it from rotating as you tighten or loosen the nut.

 

so it looks like im taking the whole damn thing apart again for the 3rd time
