Topic: Question about 22R Motor Mount Compatibility

[CoastieJack]

Hey guys newbie here. I searched the forums rather extensively before I decided to post here.

I have an 81 RN38 I picked up about a month ago. While driving on these terrible NorCal (Sacramento) roads I noticed the transmission had a lot of movement even from the slightest bumps. Took it off-roading and had to stop from how excessive the transmission was moving around. I forgot to mention I removed the shifter/transfer case shifter cover to see down. Anyways I replaced the transmission mount, OEM Toyota. That didn’t fix it. Then I looked at the motor mounts and they look pretty shot. I gathered some info that I needed this part number that fits my 81 Pickup (5140135150 & 5140235150) but they’re NLA. I refuse to buy anything other than Toyota because of my past experiences with premature failure. So a Toyota Parts guy told me to try these part numbers (1230135210 & 1230235120). Toyota says they’re for 1989 2.4 M/T 4WD and up. The only issue is they’re $400 with Tax and I don’t want to take the risk of buying them and having 35% restocking fee added to my return if they don’t fit.

SO my question is do any of you more experienced folks know if an 89’s would fit my 81? I know they’re the same engine I’m just not sure if where they mate to the frame are the same holes/placement.

Call me out if you find another related thread, maybe I missed it. Anyways thank you guys in advance.

If you wheel hard even the OEM mounts don't hold up. I tear them out as fast as I put them in. Aftermarket mounts hold up but they do transfer more noise and vibration.

Marlin has a mod where you put a bolt through the driver side motor mount to keep it from tearing apart. I get away running the stock "modified" mounts but the T-case mounts never hold up for me.

Good luck with whatever you decide.

Wow good info to know. I’ll look up that mod Marlin has and try that out. Thanks 2manytoys I appreciate the quick response

I'd suggest buying the oem mounts somewhere other than the dealer, $400 is silly. I thought 20R/22R/22RE mounts where all interchangeable, regardless of year but I could be wrong.
 
 Try giving these guys a call. They both sell and install the mounts so they should know what works.

Or as suggested do Marlins mod and keep your current mounts. https://board.marlincrawler.com/index.php?topic=95884
