Toyota injecting Tacoma frames ??

Rusty Owner/Technician Massachusetts Posted   Latest   Edited  

I stopped by a friend’s shop today and was pointed to a Tacoma on a lift. I was told that it had just come from a dealer for a “frame recall” visit.

The frame had some new plastic plugs covering a variety of oval openings. It had some moulded plastic pieces covering the opening in the box frame near the TFC where the frame transitions from closed to open. There was what looked like white lithium lube smeared on the frame rivets where crossmembers are attached.

But wait…There’s more…..

It looked to me like this white goop had been injected into the frame where it’s boxed. It was oozing outta lower holes and joints.

Is this typical? Is it some magical anti-corrosive?

Nope just packing. Those frames have no corrosion resistance what so ever. Even the new frames are just painted and that’s it. The warranty enhancement is just to appease customer loyalty. Toyota stopped making quality a while back. It is a 40 hour warranty job and hopefully they got the upgraded brake lines. I think those are better for the rust belt but that’s about it.

What is the year range for this enhancement? I know a couple people with these. Fairly late model. Both had older ones that were involved in the frame campaign from maybe 10 years ago. They were both satisfied with how Toyota handled that and remain convinced that Toyota builds the worlds most perfect vehicles. At the time I thought Toyota did a pretty good good job stepping up to the problem. I…

ZH6 is for … and I believe they have them going further than that as well. Being in Florida we see one in a blue moon. toyoheadquarters​.​com/threads/2005-2…

The white substance is a liquid wax that is sprayed into the openings in the frame to keep it from rusting from the inside out. The plus are installed afterwards to keep the liquid wax from running out until it sets up (which takes some time, depending on temps and humidity). It also keeps out road salt from splashing in when driving on salted snow covered roads in winter.

Thanks for the reply. It looked pretty messy, especially the globs of it in the front driveshaft u-joint at the pinion. Being a 50 year veteran on mechanics in the salt belt, I can say it ain’t gunna work. The metal needs to be treated BEFORE it gets exposed to the de-icing chemicals. Coating over corrosion that’s begun doesn’t work. The only retardant that I’ve seen that’s effective is various…

Didn’t Picture your air powered grease gun Injecting white lithium grease into a box frame and filling it up while you plug the holes with specially formed plastic plugs. Then smear the excess around crossmember rivets with a paintbrush

Do you know the year of that truck? My friend has a 08 were the gas tank just fell out a few weeks ago. Mount for strap totally rusted off! Never received recall notice. Dealer and Toyota customer support said he is beyond warranty and will do nothing for him.

Pics should be self-explanator. Well maybe not the one of the front pinion yoke 🙄

If that truck just had the frame replaced, I'd send it back. It already has paint flaking off from the rust!! Might make it 5 more years before it's total scrap.

I think that truck got inspected and treated per the recall.

My mistake. I was under the impression that the frame recall was just a total frame replacement.

I believe that if the frame rot was worse (perforated), it would have gotten a new chassis under the campaign

I guess I‘m expected to close this “question”. Best I can say is that the educated replies above indicated that this process is what Toyota authorizes when a frame isn’t at a point where replacement is indicated.
