DYI Improving Gen 3/3.5 vibration problem at idle

After some investigation and a little luck, I discovered that the Dog Bone and the Mount Bracket for a Gen 4/4.5 four cyl. A/T will retrofit to the Gen 3/3.5 four cyl. A/T. The Gen 4/4.5 has a much larger rubber bushing on the end that bolts to the engine and that is why you have to purchase the mount bracket to do the retofit.

Doing this greatly reduces the amount of vibration that is felt through the wheel when stopped in D @ idle. A couple other TN members have done this retrofit with the same results and I wanted to share this with the rest of the Nation. The dogbone and mount for the MANUAL trans is the same for Gen 3/3.5/4./4.5 but was changed for the Gen4/4.5 AUTO which indicates that Toyota used this new style Dog Bone to help with the vibration @ idle problem.



If you don't want to hit the pick & pull to find the bracket & dog bone here are the factory part #'s & price. I purchased them wholesale on line from





Although this retrofit was to help auto trans owners and Toyota used a different pt# for gen 3-4.5 manual,a TN member used this retrofit on a 5sd trans car with an improvment also.



12363-74130 $31.77 rod/engine (dog bone)

12313-74060 $31.10 mounting bracket



This was the best Mod/ Upgrade that I have done!

Thanks for information...I'm sure theres plenty of members that will be glad to know that!



Thats the only thing that really got on my nerves with my previous 96 5sfe automatic, was that damn vibration sitting at red lights.

Yes, the vibration @ idle was the only complaint that I had with my auto. My neighbor has a Gen4 and it only vibrated a little compared to my car. I open the hood to check out the bay and damn...there it was...the giant rubber bushing! Also, the mount bracket has a counter weight hanging from the underside to dampen vibration.

Possibility of the auto mounts and bracket fit manual trans? Or manual trans is SOL...

Dang, replaced the dogbone on mine a month or two ago with a regular gen 3 one. Wish I would've known this then. =(

Sure, the lower part of the mount that bolts to the front of the 2.2L is the same for all the engines, A/T or Manual trans. It is only the bracket that mounts on top of it (two bolts) and Dog Bone that was changed for the auto.

The purpose of this retrofit is to reduce the vibration @ idle in drive when stopped. The reason that I addressed the A/T is because with a manual you are in N or have the clutch depressed at a stop light and the stress is off the drive train and you should not feel any vibration through the steering wheel. I have not heard of this vibration problem with a manual but I could be wrong. I would like to know what effect this retrofit would have on a manual trans, so try it!



I was luck enough to have a neighbor with a Gen 4 who let me try her dog bone and mount for fitment on my Gen3 and that is how I discovered that the parts would interchange between the two without any mods including the use of the mounting bolts. I purchased a Gen 4 parts list and that is when I really had the "eureka" moment and correct part numbers.

Sorry, I have been sitting on this for a month until I heard from a couple other owner who did the retrofit and their outcome. They were also surpired & happy at the difference it made.

I see by you sig that you have a 6cyl. This only pertains to the 2.2L 4cyl.

Thanks Bear95, problem of manual trans is when you are driving with 2nd or 3rd gear and release the gas, my car jerk (at least my car)... Mount is worn but may be a bigger mount will help longevity.

Well, very good point! I have seen posts where owners of manuals have pressed in poly bushing to help with engine movement for spirited driving. It does sound like you have mount problems but by not having a manual I really cannot comment about normal movement with gear changes.

I'm interested in this mod! Dumb question but any chance to have a pic of this mod. to give some perspective of the work involved?



Oh, sounds like this might one of those mods worth considering to be on the sticky list.

There are no dumb questions, but this is too simple for pic. All you do is remove the two bolts that run through each end of the Dog Bone and then the two bolts that hold the bracket on. You reuse the bolts that you have. Easy as changing a tire or spark plug! Total time involved to change: 5 minutes or less.

So Bear95, this mod is only good for the 2.2L 4cyl's? That sucksss because I have the SAME vibration problem with my 92, but it's the auto V6, and I like to just put it in nuetral too, but then I face A) the ****'s who pull up about 3/4 of an inch away from your bumper, so if i roll, by the time i hit the brake, I now have a screaming **** at my window, or B) with my tranny, for some reason, when I shift into N, my car kinda jerks violently, and I'm actually gonna post a thread to see if I can get some help on it so as not to get off topic, but between those issues, shifting into N isn't the best solution to the vibration, but if i could replace those parts on the V6, I deff. would...
