I have a 2005 Dodge Ram 3500 2WD with independent front suspension. Can someone tell me how to remove the "front jounce bumpers" on the lower control arm and put new ones in? They are there to help when the truck bottoms out. I looked all around and these look like they are permanent, no bolts to loosen. Just the 4 rivets that surround it. I would hate to think that I have to replace the entire lower control arm just to replace these. I have a HAYNES repair manual for the correct make and year. It doesn't say anything at all in that. Thanks for any help!
