i didnt read thru this thread i just needed to say...... if you replace these..youre an idiot.



id weld the dif in before i spent $ to replace these..and since when do these ever go bad?

 

ohio... maybe they do go bad inthe rust belt...

just bolt it up and forget about it.. what exactly is the issue with the rubber eroding? theres 3 points the dif attaches... as long as its got all 3 bolts forget about it.. 4wd will still work.

 

My guess would be to eliminate vibrations with the front hubs locked. For a DD, or winter beater it's nice not to have vibrations rattling your teeth out. Mine doesn't vibrate very much, but I'm still thinking about tracking it down, whether it be these bushings or otherwise.

My truck is used primarily in winter, and just for hauling crap every so often in the summer. Often times I leave the hubs locked depending on weather conditions or where I'm going.

 

no issues with mine on my truck. And if you knew the story with my frame, and if these things generally went bad, if anyone would have a problem with them it would be me. Not to mention the amount of mud my truck sees on a regular basis. And by mud I don't mean your local watering hole with dirty water in it.

 

If you're feeling ambitious, you could probably recast a new set of bushings using the old metal pieces and some 2-part urethane rubber called "PMC-790".

 

Before you spout off >you should read
Im NOT trying to shell out the cash for the OE parts
I will be making PROPER substitutes from poly like I did with my 88





That might be how you do things....
NOT ME


^^ Yes This ^^
theres more then just a bit play in there



ALL of this what what my yota considers its duties
Winter here in the "NEO Snow belt gets us about 350" a year"
Snows about 5 of 7 days a week from dec till end of feb
Plus it does also covers my VW parts hauling needs....






The OG parts were totally replaced on the first set I made for my 88 runner
I plan to do this again
I used some poly from McMastercarr
Machined it down and away we went > Worked MINT on the cheep VS OE$

 

So to answer the questions of do these go bad... I found out that they in fact DO go bad in the 'went out in a blaze of glory' kind of way. During moderate/hard wheeling today, during a bump over an offending rock the bushing completely split and fell out of the housing. This allowed the entire diff to sag to the passenger side, which caused both CV's to shear during the next set of rocks... So apparently they do go bad? I will post pics tommorow... Doesn't appear to be any permanent damage and CV's are crapster pro w/ lifetime warranty... ANYWAYS the whole point to this long winded story... Apparently they can go bad...

And I know it was the bushing, I picked it up off the trail on our way back down, while scoping the best line for my now 2wd truck (the aussie in the back paid for itself in that space of 30min haha)

 

Bringing one back from the dead looking for pics.....

In my research of trying to find a part number for poly body mount bushings for my 94, I came across this thread. Just wondering if anyone else has done the "customize the poly bushings for the IFS diff" thing and can help out with pics and info. I figure since my 4Runner blossomed into me getting into the suspension bushings, then body mount bushings....I want to go all the way with the IFS diff bushings. I'm all about overkill. Do it right and once...and forget about it.

**EDIT** FYI, did find out that 4Crawler Roger Brown makes a custom poly body mount bushing kit for the 2nd gen 4Rnrs 90-95...in case anyone wanted to know.
