new lift and tires: bad ride
 
Just wondering about this. This is my 3rd jeep, but the previous 2 were both stock. I just put a 2.5 inch suspension lift and 32's on a 95 YJ. The ride quality was never that great beforehand, but now the thing is bouncing all over. Its almost unbearable. I can live with it, if its just a jeep thing, but I doubt anyone else would want to ride with me anywhere. I feel like I made a huge mistake, but it looks incredible. Also, the 4wd parts store installed it, I did nothing. Is there a way to soften up the ride or is this just normal lifted jeep riding. Just riding around town, every bump is an experience. Thanks

its not normal, but it could be a few things. what brand lift did you use? some springs and/or shocks are just junk and ride like crap, or it could be a couple issues when it was installed.

but very few spring under lifts will ride similar to stock, they are almost all gonna be a little harsher.

what shocks are u running i have the rancho 9000's. came with my jeep and they are adjustable, didn't know this and for the first two weeks it was hard as heck and bounced everywhere.

aness2323 09-07-2009 01:06 PM

Its a pro comp lift with ES3000 shocks. The tires are good year MT/R. They put all new stabilizers on as well. What would you do if it was yours. I am thinking of taking it back and having the manager test ride it (he owns a YJ). I cant drive this on road all the time. Thanks for the reply.

stevens243 09-07-2009 01:06 PM

Also, what tire pressure did the shop put in? If you have 32's and they put much more than 31 lbs in, you probably have too much and it won't help your ride either.

Schmo 09-07-2009 01:14 PM

yeah...check the PSI first...when I first installed my lift, the tires were filled too much and made the bumps between lanes feel like bricks!

aness2323 09-07-2009 01:15 PM

Just checked the TP. The left front had 35. The other three were at 30-31. Thats after a 10 mile drive home.

morphious 09-07-2009 01:40 PM

drop ur tp down to 30 and see if u get better ride. and then if that don't work go back and see what the manager has to say. although he most likely will tell u that's the way its supposed to be even if its not.

aness2323 09-07-2009 03:29 PM

Its better at 30, not a caddy, but better. I'm still not sure its the way it is supposed to be. Kind of feels like an old wooden rollercoaster. Thanks for the help

turdhurdler 09-07-2009 04:32 PM

Is your Jeep traveling straight or do you need to hold the steering wheel to keep it in the lane? Maybe alignment not proper or tires not balanced. Just a couple of thoughts. I am still new to this Jeep thing so I am still learning as I go.

aness2323 09-07-2009 06:19 PM

Glad you ask this. The tires are brand new and supposedly balanced. The alignment was done but all the steering components were so rusted they needed replaced. The shop warned me when I picked it up that they couldn't get the steering wheel exactly straight with the steering box being the original. The jeep drives straight but the wheel is tilted slightly. Does this make sense to anyone. They said they adjusted it like 5 times, and basically that was the best it was going to be without replacing the box, whatever that means. It does travel straight though, I dont need to hold the wheel to maintain a straight line.

Oh man I feel ya I have a 4" pro comp with the same shocks its pretty rough, from what people have told me is to go with old man emu shocks, I have just learned to live with it, I don't think Dave Ramsey would be on my side about dropping that kind of cash on shocks for comfort in a Jeep haha

stevens243 09-07-2009 10:06 PM

Ok, wait one.

For the tires, what size wheels do you have? Did you chalk test the tires?

I don't remember what a YJ weighs or know exactly what yours does but you should get the tires to the correct pressure first. 30lbs sounds about right, but I run my TJ on 15x35's on 27 psi.

Also, if the steering is "off" and the wheel won't align, something is fishy. If the front won't move enough to center the steering it shouldn't move enough to set the toe in either. Maybe I don't know enough about differences between YJ's and TJ's, but that's my take.

Once you get that straightened out, work on the shocks. If they suck, toss them and put some good ones on.

Oh, and leaf spring vehicles ride like crap compared to a more modern set up (like coil spring TJ/JK's). Just sayin' :)

same issue with mine...

Larry, wheels are 15 X 8. I set the PSI to 30. Did not chalk test anything. I assumed the shop did, I know nothing about fixing jeeps. I may look into new shocks, but this is hard since I just spent a few grand on all of this. Not sure what the deal is with the steering. They said some BS like the wheel is straight when parked but when driving it runs straight with the wheel slightly turned. They tried to say it was the angle of the charlotte roads leaning downhill, blah blah blah. It must have been something though, for them to mention it to me. It may be time to check out another shop.

stevens243 09-08-2009 08:18 PM

Well, the explanation the shop gave about centering the steering wheel works...IF you have a vehicle that you can set the camber on. The camber isn't adjustable on your jeep. As most roads are indeed capped to allow water to run off, usually the camber is set for that so the vehicle will track straight on a capped road, but will usually drift on a level road.

The centering of the steering wheel being "straight" when parked is ok UNLESS you drive a flat/level road and the jeep tracks straight and the wheel is also straight. As the jeep's camber can't be adjusted, if on a capped road, it may take a bit (just a bit) of counter steer to keep the jeep tracking straight and would explain the wheel being slightly off when driving.

Hopefully the 30 PSI per tire fixed some of your ride issues. If it's better but not perfect, chalk the tires and adjust (if necessary). Just get a piece of chalk, run it across the tread (side to side) and move the jeep over a piece of even pavement a couple three turns of the tire. If the chalk is worn evenly, your pressure is good.

Worn in the middle of the tire = too much pressure.

Worn on the outer tread - too little.

If the ride doesn't improve, ask the YJ owner at the shop. You may have adjustable shocks or just have really stiff ones that just ride that way.

Good luck.

aness2323 09-22-2009 05:15 PM

Just a followup, I took the jeep to another shop in Charlotte which said 1)pro comp springs are total shit, and 2) the only way to make the ride better is upgrade the springs (about 400) total. The old shop claims its all normal for lifted jeeps (its only a 2 inch lift), blah blah blah. Their service manager says its going to break in and the springs are stiff at first and need about 1000 miles to break in. Anyone have a suggestion, I barely like driving it now that I lifted it, very frustrated.

jpdocdave 09-22-2009 05:19 PM

pro comp springs aren't the best choice. i also suggest checking the torque on the shackle bolts, if they are rammed on with an impact gun, they are probably too tight, and will ride like crap if they can't move.

aness2323 09-22-2009 05:27 PM

does springs make more of a difference than shocks, or both equal?

aness2323 09-28-2009 07:16 PM

update: After complaining to the right people and their bosses at the company that installed the lift. They have told me to pick out either a new lift or some new springs, and they will work out the details. Should I keep the shocks that came with the pro comp lift kit and get some new springs, or have them pull off the whole kit and get a better lift kit. I was thinking OME springs. Will this alone make a noticeable difference in ride. At greater than 60mph on the highway the thing vibrates enough to scare me alittle.

motokeen 09-28-2009 07:31 PM

One Question on the tires did you buy LTB tire or radials? If you got LTBs they will ride poor on the road. Just one thing to check.

jpdocdave 09-28-2009 07:43 PM

ome springs are about the best leaf spring. to answer your question it all makes a difference. i'd have them take it all off and start again, especially since they seem willing to help. the parts are very important, but so is the install. improper install, and torque will result in a poor ride.

aness2323 09-28-2009 07:44 PM

they are good year mt/r kevlar's (Im pretty sure thats not a radial)

aness2323 09-28-2009 07:47 PM

jpdocdave: I am leaning your way. The thing is, the OME kit doesnt have half the stuff that came in the procomp kit (like the stabilizers, u bolts, and some other things). I get nothing from the shop but "its a lifted yj, thats how they are supposed to ride."

jpdocdave 09-28-2009 07:56 PM

ok, you can do this yourself: there's fourteen bolts pertaining to the leaf springs being held to the frame. bolts on the frame, and bolts on the shackles. get yourself a couple wrenches and see if you can loosen them. i'll bet they're so tight being jammed on with an impact gun you won't be able to move them. if you can't move them, or can't loosen the nut after just a decent pull, they're too tight, and the shackles aren't moving. the shackle nuts and bolts are 19mm or 3/4 (same thing) the hanger side are 21mm or 13/16 i think, i hate standard. you'll also be able to tell if they used the supplied grease on the bushings.

loosen them all up and tighten them up just tight, not gorilla fisted. for now tighten the nut up snug, and make it just tight to where you can still move the bolt head with the other wrench, but with some resistance. try that, and see if half the problem isn't their install.

aness2323 09-28-2009 08:15 PM

there is no noticeable grease on the shackle bushings at all. Some on the shackle bolts are able to be turned with the wrench on one side turning both the bolt and nut. A few of the shackle bolts are so tight, I wasnt able to loosen it even with a breaker bar.

jpdocdave 09-28-2009 08:20 PM

get them overtightened bolts fixed and see if it helps.

plac 10-12-2009 12:05 PM

ya, also make sure the jeep is on the ground when you do final torque on the leaf spring bolts.

baja 10-22-2009 06:20 PM

definitely.x2 move it up and down,if it don't give sittin there it won't give going down the road.What you have is a hardtail jeep.
