Builds 1994 BUILD OUT and LS swap! Let's Go! (2 Viewers)

I went down this rabbit hole... When I did my swap, I had ripped out the interior.. laid down kilamat and closed cell foam layer.. it helped. Still had heat and sound making it's way in. Went back to searching and gave Second Skin Heat Wave Pro – Jute with Reinforced Foil a try. This helped tremendously. I don't get heat coming in, especially around the trans tunnel area. Sound has also gone down quite a bit. I don't know your exhaust set up but on mine, no cats and to a borla oval muffler. Had the Borla XR-1 muffler on there as my first setup.. it was loud... Second one was stock Tundra muffler (sounded decent.. sounded like a Tundra).. and what I'm running now is the oval Borla. Got the sound back.. not as loud as the XR-1. But anyway, it could be a combination of all 3 layers, but I like where it's at now. AC is a lot more efficient now.

Next time I'm in Wichita to see my parents I'll hit you up. Think for Memorial Day weekend we'll be up there.

with my stock 1hdt i absolutely cannot drive with windows down as the heat that is pulled in to cabin is tremendous. everything is factory. its so bad that after 30 mins of freeway driving, my leg hair has burnt off and the dash is hot to the touch, the certain metal parts will burn u i feel lol. glass up and ac on and the tunnel is lukewarm. glass down and its like the fires of mordor

That seems pretty bad. I just ordered the solvefunction hood risers. Help heat escape. Can’t hurt.

 

[Madcrix12]

yea i live in the tropics so average temp outside is 27-32 degrees celcius

Installed the double cardan driveshaft. Seems to have fixed my issues. Now I’m concerned about a clearance issue on trans pan. Is it good it if doesn’t hit? How much clearance do you need on that side?

 

[TLC94LS]

Did I measure incorrect?? Seems a lot of center spline showing at rest! I’ll call tom woods tech support Monday. 3 inches showing from tip of splines.

How much is inside the shaft? They can make it how you want. I was telling them I am moving my axle forward an inch for 37’s when they did my front shaft and they built it with that in mind for me

Curious to know the answer here. I’m heading into the same territory here shortly haha

I drove it, and the gear noise is gone. So that’s good. Not sure moving my axle or tire size matters as the measurement I submitted was with it all installed. I’ll call Tom woods Monday. May have to make a mark and pull drive shaft off and see how much is still engaged. I’m sure it’s gtg. Just curious.

Lucky. Mine still makes the noise after getting the driveshaft. It’s just less now. Except I’m part time so I don’t care anymore. I won’t hear it at highway speeds cuz the shaft won’t be spinning haha

 

[TLC94LS]

I didn’t do the part time kit as my VC seemed to still work. I imagine you get better mpg not turning everything potentially.

 

[TLC94LS]

I called Tom Woods, about the length of my shaft (so to speak) and how much of the splines were showing. They have an entire FAQ section on it. Mine is gtg. I’m at the max end of 3 3/4 inches from center of weld to dust cap. That leaves me with 4 inches still inserted. Their goal is 3 1/4 inches showing. Just too many easy jokes with this. Enjoy!

How tight can the DC joint be to the trans pan. I’ve got about 1/4 to the pan. Is that good enough. I’m not sure it flexes too much right there. Obviously I’d like to have more. Any opinions on this?

 

[TLC94LS]

Here’s a picture. The metal showing on the drive shaft was from install. I’ll hit it with some paint to see if it rubs in the future

 

[Broski]

The picture is not clear enough to tell.
But I think 1/4” is to close the motor mounts can have that much movement.

 

[Broski]

At second look I can see it better.
IMO it’s to close.
@landtank sales a all Toyota DC front driveshaft that utilizes a smaller U-Joint
That may work better $$

 

[TLC94LS]

Yikes well that sucks. I could try clearing the trans drain pain a bit. I could call land tank and ask what the circumference of his cardan joint is.

You may have to do both
For sure the @landtank DC is smaller

 

[TLC94LS]

@landtank are you able to give a circumference measurement on the DC joint you use? I didn’t see a contact us link on your website. Thanks.

Get a hammer? s*** I may be in this boat here real soon

Not much you can do, since the trans is mounted to marks adapter to center diff that relationship is pretty set. You could massage trans oil pan, not sure how much of a no/no it is to mount the driveshaft the other way?
