Early T-18 diff in AE86
|
Thu, 09 September 2004 23:18

 |
Recently installed my new t-18 into the back of the car but there was a slight problem. It didn't have brackets for the swaybar, causing me to take the swaybar and put it in the boot lol...
i came to the conclusion last night with a bunch of trd-spec fellows that this is causing my car to very easily lose traction and feel as if my car is sliding even when im not turning...
now, problem is, what is the best way to reinstall the sway bar? i really dun wanna take the diff back out and weld the swaybar brackets on (i will if no other choice)
has anyone had this experience and how did u solve this problem?
also trd-spec peeps claimed that my speedo will be out of wack, will an auto electrian fix this up?
cheers for the help

Getting the mounts welded back on while the diff is in the car shouldn't be a problem. Just take it to someone who can weld.
The speedo will only be out if the ratio of the diff is different from original. There are companys that make devices to alter the speedo. There was one around seven hills but can't remember the name now..

nah i didnt do anything, the later t-18 diffs came factory with sway bars
looks like a neat mount, i have no comparison of a 86 diff though

Its an early diff with a 4.1 ratio. Rather than the S series 3.9.
Someone else can do the calculations on that change
As for the mounts, just take an angle grinder to the old diff and then weld them onto the new one.

yep weld the swaybar mounts on, straight forward job for a competent welder.
dont drill anything!
also i would have thought no swaybar would increase bodyroll but not decrease traction?

I'll cut the mounts off your old S-series and give them back. Then you can weld them back on.

He is talking about cornering traction, not straight line. I.e. when you go around a corner you get more body roll and wheel lift, therefore less traction (effectively)

U should weld the sway bar mounts on. It'll be much stiffer. I know of people who had this problem; whatever you do, do not use hoseclamps, they are ineffective

Latter T18s axles with the sway mount already on them?
Which year/model Australian car can we rip apart for them?
Attchacing disc brakes too it by welding a bracket for the caliper? Whats the best or some most common brake types used? FC3S?
And what is the diff ratio?

shiri just get the mounts welded on
u bolts will never be as safe as the stock mounts welded on.
the fc3s brakes and commonly used for the front,
diff ratios are 3.9 and 4.1 i think

The standard early T series diff ratio is 3.7 and the S series is a 3.9.

theres a tech article on a disk upgrade
isnt the t-18 diff same housing as ra23
so then the article would apply to t-18 diff to being a t series diff

i think i got a T-18 earlier rear end as it doesnt have any swaybar mount on it...i wanna change the ratio of it....this can be done by searching for a TA22 diff and swap the gears over??
is TA22 ratio 4.1?

Hey guys..
sorry to dig up an old thread... but just want to know if its true that when doing this conversion the t-18 handbrake cables need to be taken out and replaced with the sprinter ones coz they're too short???
or sumthing along those lines??
just that my car's at the diff mechanic and i wanna suggest that if there's any problems,
thanks.

you use the t18 hand brake cables and swap the single cable for a t18 one

the "Hand brake cables" consist of 3 cables, front (from the handbrake lever to about a foot down the transmission tunnel) and right and left (from the front cable to each wheel)
You will need to use the T18 right and left cables, and probably the centre cable as well, so you can get correct adjustment. This is what I did, but I did a JDM AE86 T series diff swap. I've never done a T18 swap, but i assume it is similar.

Another alternative is the U bolts; the Whiteline rear stabiliser bar package for TA22 includes some hardcore U bolts as TA22 did not include rear stabiliser from factory.
Maybe Whiteline will sell those brackets seperately, they shold be perfect?
