Quick question to see if anyone has tried filling their rear diff mount with urethane yourself. there's a guide out there but wanted to see if anyone else tried it

I had seen some do it in the past. The used to be a tutorial online back in the day. Another method is to make is solid, but welding a piece of metal in there on both sides.

I made one out of 70a two part urethane. It didn't last very long. Bought a new one from Toyota.

Some guys have also had success with the polyurethane construction grade adhesive in the tube.
It's quicker and easier but probably won't last as long as the method in the link above.

Yeah that's the guide I was referring to. Guess no one has had great luck with it. May do it this summer as a temp measure because I'm starting to get a clunk, but seems the Toyota one will last alot longer

I filled mine with PL Poly construction adhesive. Although I haven't checked it recently, I have no reason to believe it isn't just like I left it. My engine mounts using the same stuff have held up like 8 years now. (did them at the same time as the rear diff mount)

^ Was there a notable difference after it was filled?

When I did my engine mounts it was definitely stiffer but I've never thought to bother with rear diff.

Hey Chris how long did you leave it to cure?

My diff mount is starting to go on my ST205 so I'm going to give it a try one of these days. I picked up a spare mount that I am going to try and fill.

Is there an aftermarket all-poly mount avaliable? This should be the same between the 185 and 205 yes?

I can't remember, but there was a company making poly mount kits for the 205 engine, maybe they have diff mounts?

I haven't been able to find an all-poly aftermarket mount available from anyone. There are a couple guys making engine mounts, but not diff mounts. Yes the 185 and 205 are identical diff mounts.

Mario sells a solid aluminum diff cushion in a variety of anodized colors as does Klue IIRC (Klue's aren't anodized though).

My motor mounts are filled with some poly from Lowes. Think it said 60A. Either way, it's holding up so far. I just made sure to clean the old stuff before filling.

Only aftermarket I've seen is the aluminum ones.

As for will it make a difference...if you look at yours and it is disintigrated/cracked to all hell, then yep it'll definitely make a difference! Eliminates one of the main source of the 'rear end clunk'.

As for curing time, I left it for about a week. A few days is probably enough though.

C-One made a stiffer rubber mount and you used to be able to find it on rhdjapan.com

As a side note, from the research I did, the poly engine mounts for 265/185 will also fit 205 with a tiny bit of fiddling.
