Issue with Solo Motorsports Tundra Steering Rack

I just installed a Solo Motorsports Tundra Steering Rack with the Inner & Outer Heim joint tie rods on my 2017 Tacoma. Now I’m having huge bump steer issues. When the suspension compresses it goes Toe Out by 3 inches. When the suspension droops it goes Toe In 2 inches or so.
Tundra rack is the same length as stock, measured to verify. Tie rods are 9.125” long as they should be by Solo Motorsports info.

Solo Motorsports is saying I have too much pre-load on my Fox 2.5 Shock. But the shock doesn’t change the geometry just dampening.

Never had issues with truck til this rack and tie Rod setup was installed.

If anybody has any ideas I would be greatly appreciated.

Thanks

 

Are the inner tie rod heims able to swing up and down?

 

Yes, it turned out that the Tundra Rack on a stock width rig is set too far aft and when the suspension is compressed or dropping the toe goes in or out causing major Bump Steer. Removed Tundra Rack and installed new OEM Rack problem was solved. Major mistake trying to install Solos Rack. Had to buy new Spindles and steering shaft since I modified them. Thanks for the question I was wondering if this post was falling on deaf ears.

 

Damn

 

He who dares wins! (sometimes).

 

Yikes. I haven't heard this before.
I wonder if their rack is different than the others out there? I am in the process of doing a Tundra rack and heim tie rods. It does sit back about 3/4 of an inch more than the oem unit.
Glad to hear you got it sorted. Hopefully I do not see the same issue

 

I ran the Tundra rack with stock tie rods, and also had similar measurements with my +2 lt kit. Had 3" of toe in at full droop.
The bolt-in Tundra rack is not in the stock location, thus causing much more bumpsteer than stock.
Doing heims also changes the pivot points, thus adding more bumpsteer.
To fix it, youd have to move the centerline of the Tundra rack exactly where the stock rack was.
I have the measurements somewhere, but I wanna say the tundra rack sat like 3/4" back, and 1/2" higher than the stock rack location.
I now just run a stock rack for this reason lol

 

The rack is the same as others who sell the modified tundra rack. The issue is that the offset ecentric bushings allow it to bolt into the stock rack bungs, but thus place the rack in a different spot. Not much else you can do besides cutting out the stock bungs, and using the stock tundra bushings with relocated frame bungs.

 

I see. Appreciate the explanation.

 

Well damn I’ve been considering the basikbiker tundra rack but I don’t want any issues so I’ll mark this off the list

 

With stock travel I ran the Tundra rack for around 8 mos and the bumpsteer wasnt really noticeable, but once I did Lt it was severely noticeable on/offroad since theres that much more travel.

 

So does it need to be combined with JD fab steering pump or do I keep the stock rack?

 

The stock pump works just fine. I eventually blew the seals out of the rack wheeling, so personally I wouldnt want any more ps psi anyways.

 

What steering solution do you recommend?

 

Decent video to get your head around this stuff.

 

Stock racks are easily replaceable, dirt cheap ($120 at the junkyard) and hold up fine. Ive been beating on a 200k mile junkyard rack for the last 8 months and havent blown it yet somehow.
I blew the Tundra rack while running stock tie rods, and currently run the same tie rods and have just bent like 4 of them the last couple of trips, and the rackbis still fine.
The real solution is swingset steering, full hydro, or straight axle. Unless 74weld comes out with a "bulletproof" steering rack for $5-6k

 

I moved the tundra rack forward about an inch after not liking how it went into the stock location. Fully heimed ends on the rods and I don’t feel any bump steer or have toe in out problems. Alignment procedure went good. Must be some bad geometry going on

 

@Basikbiker might have some input

 

I don't believe the Solo Motorsports Tundra rack was ever meant to be installed in the stock location. From there web site.

NEW Cam Bushings are provided to allow for a easy install. These bushings keep the factory mounting points on the cross member. No more cutting out the old barrels. We will still provide the stock rubber bushings if you do not want to using the cam bushings.

This is not a direct bolt in and requires fabrication skills to install. The frame will need to be notched for steering shaft.

 

Why did you choose the Tundra rack vs JD Fab slide rack?
