i do alot of muddin around here in these parts....mostly slick red clay.....none of that mud bogging...(going through 2 or 3 ft of mud)....i just like to spin my tires and get my truck allllll kinds of nasty....my question is....on my 1980 yota 4x4 20R....completely stock....except for my 31x10.50x15 TSL's (which are great)...i want to know...usually what is the first thing to go...(or break)...on those old trucks...everything seems to work fine...other than the old tired 20R...but it still runs strong...the 4spd tranny..seems to be just fine...except i need a new clutch...other than that..those are the only problems...my dad doesnt like me goin muddin...cuz he thinks i will tear somethin up....but all im doing basically is spinning my tires....lol..thanks in advance

 

i cant see anything wrong with spinning your tires. maybe you could get some mud up somewhere to block a sensor or something...

 

yeah i've already had problems with the tailights...(mud and rocks hitting the wires and what not)....my dad thinks somethin mechanical will give sometime...because of the trucks age...and owner before me..(rolled it once onto driver side...jumped into mud holes...all kinds of stuff..)...lol...anything mechanical any of you guys have in mind that might go wrong

 

Not really, First gens are pretty basic and since your only running 31s id say nothing should really let go, if anything were to go id say its just from wear and tear since its an old truck.. the only things that come to mind are the U-Joints.. rear drums could fill up with mud, water/mud could get into the intake.. but those have nothing to do with the age of the truck.. that can happen in any truck. The biggest thing id say with a first gen is if you let it sit with wet mud on it, it will probably rust out pretty quick... make sure you give it a good wash every week or so.

 

my $0.02:

IF you hit bottom and grab traction you may bust a u-joint or the ears around one.... next in line would be an inner axle shaft in the front IIRC

 

yeah most of what i do...is just some shallow clay in fields....there is a place around here called Harkies Island...it gets pretty BAD after it rains...usually about 1 1/2 ft of nothing but mud....only been through there when it was that bad once...and i was the only one to not get stuck...AND I WAS ACTUALLY TRYING TO GET STUCK!!!.....f-in toyota.....there too good..LOL..and i also have another question....whats is IIRC????????...i've seen it quite a bit and dont have a clue what it is

 

IIRC = if i remember correctly... memorys not perfect.....
