Jounce Bumpers

[Rockledge]

OK, so while I'm waiting on a couple of reinforced mounts from SHONUT so that I can wrap up a clutch job, I've decided to continue to work on the front suspension a little bit while I have things apart. I'm going with Eibachs and Tokicos all around with new mounts, bearings, washers, etc. The dust boots on the car look to be in good shape and my intention is to re-use them.

Well, late this afternoon I was able to pull the drivers's side front off and I found that the "jounce bumper" is completely shot. To be honest, I hadn't even thought about those little buggers. I realize now that I'm probably going to have to replace them all too, but I have a few questions first:

1. What exactly is the purpose of the jounce bumper? I assume it acts as a sort of cushion or bushing when the strut "bottoms out"?

2. Do I have to use the ones from Ford or can I get them at a parts store?

3. Or how about this: Can I use a couple of my SHO's old rubber strut rod end bushings for the bumpers? I just happen to notice they are about the same size (maybe a little shorter but the same width) and fit on the strut in the same manner as the bumpers do.

TIA

1. Yep, it keeps you from damaging the strut from bottoming out.
2. I woud assume as long as it fits the strut and is a comparable size as the factory one it would work.
3. See #2

I bought a boot kit at canadian tire up here that included a brand new boot and jounce bumper for 22cdn.

An elastic cushion used to stiffen the suspension gradually as it approaches the end of its jounce travel.

I got some kyb ones from a local parts store that fit perfectly. Integrated bump stops and dust boot.
