#1560136 620 Rally Build

Posted by Stoffregen Motorsports on Today, 07:02 AM

I'd love to build a 620 rally or desert truck. Sounds awesome.

 

You may consider a Toyota 4x4 rear axle right out of the gate. Gear ratios are more plentiful and very cheap. Lockers, limited slips, axle shafts, disc brake kits, etc are all relatively inexpensive on a Toyota axle too. Depending on the width you desire, I would probably start by looking at a '87-'95 rear axle. It should be about the right width and it's a lot stronger than the earlier housings. A Tacoma housing can also be used, but they are a bit wider still. Be careful choosing a Tacoma housing as the most prevalent out there has a 8.4" diff, which is harder to find parts for. You want the regular 'ol 8" diff.

Do you have a link to the site where you saw them?




#1559925 This how you attach rear sway bar to axle? 720

Posted by Stoffregen Motorsports on Yesterday, 07:06 AM

That's why I gave the McMaster-Carr link, so he could source the right u-bolt the first time around.

 

The don't need to be "axle" strength bolts as they aren't holding the axle in place, only the sway bar. So they can be much smaller diameter, like 3/8".

I rather like the pic in the instructions. The other way looks really clunky.

 

Just be sure not to pinch the hard brake line when installing the bolts.

Good call. In a collision, the first thing is always to check the dist rotor and cap. When jarred, they can contact each other and break one or both.

That lower portion of the bracket is for a kick down or TV cable on GM automatic transmissions.




#1558409 Frequency noise coming from rear susp. or drivetrain.

Posted by Stoffregen Motorsports on 16 April 2018 - 08:18 AM

U joint failure sounds a lot like rubber bushings squeaking.

You can get them at Nissan.


I had to buy a 10 pack when I got mine.

Funny how nobody ever thinks to try the Nissan parts department.

Thanks.

 

I have never used an LD28 in diesel form, but i have used plenty of the LD28 blocks and cranks to build 3200, 3300 and 3400 cc Z car motors. The last one I built was for Hoover Chan of TurboHoses and Noble supercar fame. It made 650hp.

 

That was a long time ago. I don't build engines anymore (if I can help it). I do mostly trucks now and a lot of V8 swaps.




#1557316 2nd gear making sound

Posted by Stoffregen Motorsports on 11 April 2018 - 07:06 AM

You're assuming that the noise only happens as described. I assume nothing until all the variables are whittled down.

 

Here's another possibility, that the bellhousing bolts are loose and by pushing the clutch pedal, it actually moves the trans, causing it to hit the body.

 

That was more of a joke, really, but you just won't know if you can't see the vehicle in question.




#1557313 620 LWB with wide 18's?

Posted by Stoffregen Motorsports on 11 April 2018 - 06:48 AM

In the offroad world, it is not uncommon to build the truck around the tires, but that;s where the proportion comment I made earlier comes into play. If you want t use 42" tires, then the wheelbase and track width need to be "X".

 

Same for the wide ones in the first pic here. The truck is too short for that wide of a stance.

 

Fender cuts can be made to look good and retain strength, but I rarely see it done right. Guys usually just hack it out and call it done.




#1557051 Bonded Titles?

Posted by Stoffregen Motorsports on 10 April 2018 - 09:58 AM

CA DMV has complete discretion over waving back fees. I bought a Chevy C30 a few years back with $1700 in back fees and I walked out paying only $40.

 

In that case, I explained that the truck was sitting, not driving, while the fees accumulated.




#1557050 Bringing a sitting car back to life!

Posted by Stoffregen Motorsports on 10 April 2018 - 09:56 AM

In the context of bringing a long sitting engine back to life, adding ATF to the oil is not a horrible thing to do. It's nothing like running without an oil pan.

 

If you're skeptical, don't do it. But I have done it many times on old engines and it does help clean the crankcase.




#1557034 Bringing a sitting car back to life!

Posted by Stoffregen Motorsports on 10 April 2018 - 07:59 AM

I was going to say yes, but after thinking about it, it's probably the best time to use a good filter so that stuff that breaks loose gets caught in the filter.

I use ATF in the oil as a flush. When doing an oil change, simply substitute one quart of oil for a quart of cheap ATF. It is highly detergent and will help scrub the gunk out of the rotating assembly. It also helps free up stuck rings and the pressure relief valve in the oil pump.

 

It may smoke while it's in there, but that's normal as it slips by the rings. Run it for a couple hundred miles if you want to.
