Shakey, shakey, hoppy hop...

My 99 has become worse lately with this problem.

It hops really bad when I press on the brakes, dont know if its the calipers or the shocks???

I also have a nice shake during most cruising speeds...it has become very annoying, hoping to have time this weekend to tear into it.

Any ideas???


While I'm asking for help about my problems, I also have a very bad thump sound coming from the front drivers side area wenever I take a turn and hit a bump at the same time???? WTF

Thanks in advance for any help!

Warped rotors , out of round drums and maybe a tire seperation .
Check the front knuckle joints or ball joints

Ball joints would be my first guess. The stock ones tend to dry out over time since they don't have grease fittings. If you don't get them fixed, they'll eat up some tires.

Yea, I have new tires and rims...gonna get them checked after this weekend.

I have disk brakes so I think I going to just put new rotors on this weekend, since it has not been done in 3-4 years.

I have new ball joints that I need to install....no time

I have also heard about the axle seal and the spring pack.... anybody know more about this???

You need new ball joints, and while you're in there you need to replace the axle seal. It's easy if you have the tool to set the depth, or you can make your own tool out of plumbing supplies. And that thumping sound when you hit a bump is your sway bar, replace your sway bar bushings with a set of Energy Suspension bushings.

Been there done that got the T shirt. This fixed all of my problems which you are describing.

Do you have any info on the tool for the axle seal, or a link on how to make one.
And did you do your own ball joints and if so, what will I need to do those. I already have them, just need the time to do it!!!

Here's a link I found that looks pretty helpful. I just had the shop do mine while it was in there for new tires...it was about 5 hours labor, but I don't have the time/garage space to do it myself right now.

Awsome, Thanks!!!!

Still need to figure out why it hopps at most speeds and while I am braking?

Could my drive shaft be out of balance?

It hops cause you need new ball joints!!!!!!!!!

I don't have any info on the tool, a buddy of mine brought it from the shop he worked at. We did both sides of my truck in an hour and a half...

Other than the axle seal tool, no special tools are needed. You're going to need to borrow a ball joint press from the auto parts store, it looks like a big C clamp.
