Sounds like you and me are having the same problem. http://www.jeeppatriot.com/forum/16-suspension-tires/316578-moog-coils-2008-4x2-fwd.html

I haven't sorted mine out either. Hoping someone on the forum has been able to sort this out and can lead us to water

BTW, what year and model is your Riot?

 

Same as yours, 2008 FWD.

I checked the sizes of everything prior to installing and made sure everything matched up. The only thing that was an upgrade was the Moog sway bar endlinks.

I'm going to order the parts for the rear this week (tax refund incoming!) And install this weekend. And see if raising the back end up helps.

I'm glad I paid extra for the 1 year of alignments, so I can take it back afterwards.

Let me know what you find out man after you raise of the rear end. Mine is lifted in the rear as well with the Moog coils. If I get time this weekend I may actually pull the cv axle myself and see if it really is binding.

 

2008 Jeep Patriot, Manual Transmission

How unlikely same issue, just replaced Struts and Lower Control Arms and now I have a vibration during acceleration. Had new transaxles installed and still have the vibration issue. If anyone has any ideas of have solved this issue please reply.

What are you running for tires? Are they OEM size or close? Off size tires can cause problems. Are you lifted or any other suspension mods?

Just food for thought here, but I once had the opposite problem as you -- in a way our problems seem to rhyme. I had a set of tires that I took off our Wrangler because we got the "death wobble." When I put them on my Grand Prix I got a vibration when driving along between 55 - 70mph; there was no vibration when I was accelerating. When I got rid of those tires the problems went away. It was just a bum set of tires that wouldn't work anywhere.

IMHO, if it was the tire balance I'd expect the vibration all the time.

 

Did you have an alignment done? If not, that'd be first on the list.

 

Running OEM tires, Brand new ones BTW, car was aligned and all wheels were balanced. Still have the vibration issue, does not seem to occur in first gear, but most noticeable in second and then becomes less noticeable as you go through the gears. What's also strange is sometimes it doesn't occur at all? When you let off the gas or push in the clutch it goes away.

 

I once had a bad belt that I mistook for a bad tranny. Gave me what felt like a grinding in 2nd gear (it was a 3-spd manual).

 

Check for play in your CV shafts

 

Hey everyone, I've been away for awhile, but finally got around to taking care of suspension issues that have been plaguing the Pat lately.

On the front end, replaced the strut assemblies, lower control arms and sway bar end links. Then I took it for an alignment.

Now, during moderate to heavy acceleration, I have vibration coming from the front end. If I tromp the gas, the Pat wants to go every way but straight.

I also noticed that the front end sits up fairly high, higher than it used to. I'm guessing this is due to worn rear suspension components, which are getting taken care of next week.

But back to the issue at hand, what could be causing the front end to shake under acceleration? It didn't shake at all prior to replacing the aforementioned parts. Thanks in advance!

Any updates? I just changed lower control arms, struts, and sway bar end links. I also installed the 1.5 inch Daystar lift.

I am having the exact same symptoms as you. The front end gets squirrelly if I hit the pedal hard ( goes every way but straight ). It also shakes and shudders under load at any speed over 15-20 if I give it gas.

I didn't have any of these symptoms before changing the parts out so I'm positive it's not " spark plugs / performance " related. It feels like maybe a CV shaft but I'm not positive.


Hopefully someone can lend some advice. Thanks in advance!

 

Did you get this resolved? I have same issue. Basically changed everything up front, struts & all axles changed twice. Axles seem to have a lot of runout when i spin the tire.

This is a fairly old thread, so you might not get a response from the other posters.

If you've changed struts and axles, you may need an alignment.

Make sure the axles are fully seated in the transmission.

If you have a FWD CVT and used aftermarket quick struts, they may be too long and causing the passenger axle to make contact with the control arm mount on the subframe:

Thank you, i have the manual transmission and used aftermarket quick struts. Can this be fixed with an alignment or does it require the factory mopar shocks & springs? Thanks

 

Well I’ve had the front struts and cv axles replaced twice and still not fixed. Changed all front brake parts and tie rods, linkages, etc. it sometimes feel like the tire is too narrow and can’t keep contact with the road. This started happening after original struts were replaced. 2 mechanics and myself haven’t been able to figure it out. Wondering if it needs a camber kit or some caster adjustments. Only thing I haven’t replaced is the wheel bearings but they have zero play or noise. Hopefully I don’t have to buy the mopar shocks and coils because I’d have to buy all the bits and pieces again because Firestone threw them out lol.

 

Also, when the wheels are on the ground nothing is even close to hitting. (Cv or strut not hitting other components)

 

Well am not the only one with that problem. I changed the rear control arms, sway bar links, brake caliper. And now replacing the front control arms, sway bar links and tie rods too. Hopefully after the alignment. It will be fixed. Only thing left to change are the struts and axles.

 

What is your transmission and engine? Also do you have OEM struts or aftermarket? Took mine for alignment today just gonna drive it as is. Still nobody can figure it out

 

What came from the factory for struts.

What came from the factory for struts.

did it happen randomly or did you have work done?

 

Randomly. When I replace the back end I had the alignment done. Than after winter it stated worst if I turn left and hit the gas.

 

Unreal, mine happened after replacing front struts. Seems like an alignment issue. I took it to a good alignment shop today I’ll let you know if he finds anything

 

Thank was your struts bad. I been looking at mine but they look ok.

 

Yes, ever since the front struts is when I had the vibration when accelerating.

 

Mine is a bad inner tie rod putting the new tie rod on tonight I will late you know if that fixes mine

 

Sounds good, hopefully that is it. I just got mine back, still shakes a little in second gear but at least 1st & 3rd doesn't shake anymore. Basically I think the alignment and camber bolts helped. It was not resolved 100% though, the mechanic swears the firestone tires are bad. However, they only have 3000 miles and would have been bad since they were new from the factory. Just going to drive it as is until something breaks.

let me know if tie rods fixed it. You will probably need an alignment after to know for sure.

 

Well got the tie rods on. It took alot of of the vibration out but now am going to need a ball joint. . At some point am going to run out of part to replace, already replace the everything in the backend. Now am on the front end
