Just had a Toytec Ultimate Lift installed on my 2007 A/T 4x4 and I noticed a vibration I can feel on the pedals or floorboard every 5 seconds. It will be quite for 5-7 seconds, then for 5 seconds I can feel a slight vibration. I don't feel it in the stearing wheel and it doesn't see to matter how fast I'm going either. I also tried to see if it stop if I took my foot off the gas and it doesn't. Any ideas what it could be???

Only thing that comes to mind is to ask if you had a front-end alignment done after the install of the ToyTec lift? Also, have you had your tires balanced lately?

If you did have it aligned, you might go back to the shop and ask them to make sure all the bolts are still tight and everything looks okay.

 

[Capt Sensible]

First things first, after a lift you have to get an alignment done. I'm assuming you've done that. Tires need to be balanced? Check your lugnuts make sure they're tight. Go back in there and double check your bolts on the suspension.

Those are the usual suspects. If it isn't any of those, could be a CV Joint or heaven forbid your transmission. I actually just recently put a toytec ultimate lift on as well, and not too long after that my torque converter went out. I don't think they are relevant to each other, but still I was getting weird vibrations. But I could feel mine in the steering wheel, and as it got worse I could feel it all over.

I assume you have to be moving to feel it?

I had a vibration lately but not right after installing the toytec.. after many offroading and several jumps.. the vibration showed so i took it to my wheelshop and i needed both alignment and balancing.. pay them a visit and check it out..

 

[mnik]

I just spoke to a local shop about installing a lift and the service manager mentioned that there will be a vibration. He said for some reason they've experienced this on the FJ's. He thought it was because the driveshafts are so short on these. Want to lift mine, but don't want vibration. thoughts? is this common? if so, are there simple fixes?

 

[HUGO STIGLITZ]

This must not be common or we would see and read about it more here....

 

[markthomas1969]

I too also have this vibration(constant) but goes away above 50 mph, due to driving 50 miles before getting alignment.
I am going to rotate the tires this weekend and see what happens.

 

[markthomas1969]

Were you ever able to determine the cause of the vibration?

 

[bandi]

How much lift did you dial in in the front... you could be over the 3" mark, and causing some front axlew vibes... try a 1" drop diff' kit if soo....

What about tires, did you upgrade them also ?....

grease the driveshafts too if you have not, and some in the slip joints but don't overfill !...


ohhh, and I have 4" lift currently with a 1" drop kit, no vibes at all....

 

[markthomas1969]

What kind of difficulty could I expect when installing the differential drop kit?

 

[bandi]

None at all really....

Since it was an Incredible day last Sunday here at
the jersey shore, warm and all, I added my Toytec
Diff' drop kit, along with a few other things...

The Drop Kit Went in quite easily, and even though
they say it's a 1" drop kit, it actually only drops it
about half amount, since the kit provides 1" spacers
for the leading edge of the axle mounts, but the rear
mount stays the same, however, I did read
somewhere about trimming the rear mount to gain a
tad more... It has seemed to do what I needed, by
the looks of the CV angles...

Then replaced my original ball joints that were a tad'
loose, and also adjusted my coil overs back up and
inch, since I dropped it and inch over the summer
when I had the issue with the CV's grease seeping out
of the boots from to much of and angle on them...

Now even tho my front was lowered an inch, my rear
OME 896 springs were sagging to where the rear was
still lower then the front, so after raising the front
back up as I said above, I decided to add my old
daystar spacers back in to level the FJ again...

Well, after all was said and done, and I measured my
FJ against my wifes, I am at 3-1/4 lift in both the front
and rear, having the original stock rake... Looks great
to me, now I just need the front end toe set, and my
new tires mounted...

I am unhappy with the OME rear springs, and I will need
to replace them... From the looks of the springs, it seems
they have failed, not broken... All the coating on them
have spidered, cracked, and rusted bad, and the springs
have settled beyond the point they should have, since
the FJ sat lower in the rear then the front, even with the
front set only 2 inches over stock, and for being the
OME 896 heavy springs...

I was thinking of going to 897's like Mir' did, but it's a bit
more funds then I can toos right now into the FJ... I am
unsure if there is a warranty on the springs, or who I
could contact about it, specially since I bought them
from Jim_D in the summer of 06', but they were new, it's
just that I did not by them myself...

OK, The INSTALL !...

OK... Still never reinstalled the skids yet, but
ToyTec does give you the needed spacers to
do that too in their kit, something that you
don't find in other brands...

I am also looking into trimming the rear mount
a tad to get a little more drop, more when I
figure that out...

First, you need to remove the skids, in my case,
front bling, front tin and middle tin...

Here is a shot on the front mounts that the
spacers get installed on...

Here is a shot of the rear mount, which I read on
a forum, or maybe it was in Toy'Owners Mag, that
you can shave the mount to give you a 1/4"-3/8"
more drop on the diff'...

An overall view of the mounts and diff'...

I put a jake under the diff' in order to lift
and lower the diff' easily for removing the
bolts and adding the spacers...

I used a 22mm socket to loosen the mount bolts,
with a 19mm wrench up on the top to hold that end...

Here are the two bolts after I removed them with
the bottom bushing plates...

Here are the 1" spacers(round), and also the stock
bolts and the new grade 8's that toyotec provided,
along with washers and nylock nuts... Also here you
can see the skid plate spacers(square) and bolts too...

Here you can see the the spacer installed, making
sure the upper and lower bushing plates are back
where the go, along with the new washers too...

And here they are, all installed !... Very easy, only
about a 1/2 hour job really, unless your taking some
pictures.. ...

Then reinstall the skid plates with the included 1/2 inch spacers....

Once I find the article on triming the rear mount, I
will finish' er' up !...

i have this lift, no vibrations, no issues

 

[markthomas1969]

Something I just thought of... while looking at what came off in comparison to what went in, I noticed one difference. The factory fronts had a rubber gasket looking thing that goes in between the shock mount and frame. About an 1/8" thick and same diameter as shock mount with 3 bolt holes in it, please tell me I was not supposed to re-use that?:thinkerg:

 

[markthomas1969]

Just ordered the diff drop kit.

I don't know, but I would assume if your three nuts are screwed down tight at the top of your shock, that 1/8th of rubber wouldn't matter.

 

[markthomas1969]

For sure tight, I was just thinking that if it was there to start with then there must have been a good reason to have it there. Too bad I did not think like that when I put the lift in.

Does the vibration go away when you shift into 4x4?

I work at a Toyota store and vibration's are a common issue after installing lift kits on both the FJ's and the Taco's. The lift puts a greater deflection on the front CV Shafts causing a vibration. When you shift into 4x4 and it puts a load on the front shafts the vibration goes away.

Something worth looking into.

 

[markthomas1969]

Did it, so now that makes 1 lift kit and a diff drop kit installed by one guy, crappy hand tools ,in an apartment parking lot. Not too shabby! Going to go and gas up and see what happens.:rocker:

 

[markthomas1969]

Much better now!
