It's wierd that in the USA you can buy light vehicle (car, ute, 4wd, suv) batteries are places like Costco, etc. The Bunnings hardware stores here in Australia do carry a small range of vehicle batteries. Auto parts stores are the most common places people get new batteries from, plus Battery...
Never worked out what the correct one is. TBH the AC has never worked in my 80 since I bought in mid-2011 and it's not a core concern, but I'd like to fix up the damaged wiring so at least it's there and possible to re-enable.
There are places that make valve shims. We have one here in australia called Precision Shims which I have used last time I did the shims on my 80's 1hz motor at 600 k km's almost 8 yrs ago (yeah since then it's been driven a lot less) because I needed some thicknesses that couldn't be achieved...
Top of lower spring seat to bottom of bumpstop at the front. There is a 'factory' measurement for this but not sure of the number. Both sides should be close to the same.
If you use factory rear arms the quality of the bushes is that of genuine toyota. Do *NOT* ever use poly bushes for those! Or the front arms, or panhards, or swaybars.
4wd aftermarket places are pretty much all built on hype, and if they can live up to the hype they survive. Look at Australia - ARB and TJM are the two market leaders followed by Opposite Lock and some others.
ARB and TJM definitely run more on hype that quality, and ARB's staff treat customers...
I personally have bought from Wits End several times and never had a problem, but I'm in Australia and don't have $10000+ to splash on 4wd bling things so I buy what I actually need.
For the record, I don't run any brake pad shims. The front brakes are 105 series pads that are bigger in area and thicker than 80 series pads and can't be fitted with shims. Front brakes do most of the work so nearly all the brake dust generation happens there.
Also for the record, since OEM...
Flywheel bolts should *never* be bare dry! If a threadlocker isn't used they should be lightly oiled. I don't use anti-sieze on them as (like head bolts, etc.) they are a 'critical component'.
Just being able to afford to re-register and insure the 80 will be enough of a Xmas gift this year now that I've got a home loan for the next 30 years and have re-organised finances around that 8-) Rego runs out in a few weeks.
Right side, seems to occur where there is a rapid change in road undulation. Running buds customs arms for 4 inch lift. I can't get it to occur if I jump up and down on the right side of the bullbar violently to make the suspension load up.
If I had a go pro or similar I'd strap it underneath...
