Looks like the 1 pc did not solve my problem, it only shifted it to a higher rpm. it now vibrates at 80mph and over which i suspect is 1/2 the actual critical speed. I took a road trip yesterday and the drive was enjoyable except at 80mph and over. Suffice to say i kept it 70 mph most of the...

No, the ones pressed into rear knuckles are still available from toyota, the serrated ones are for the rear arms on inner side. The ones for the rear knuckles are listed below. I bought about a year ago from Japan.

Its cool, looks like they listened to me, I requested for the bushings on front and rear arms. Maybe a whole bunch of guys asked for it too. So how was your experience ordering these? Did your local dealer jack up the price ?

is it ok to use a M type front half with V type rear half ?

Guys, I was going through the SUpra Heritage Parts program, and there is a propeller shaft, they listed two types of joints. Mine came with the V joint (Staked). Any idea why there are 2 different designs? I would think the M type is easier to service.

I took it from 60mph to 75mph for a few seconds today. No vibrations.

Amen to that, i saw on some websites listing a 44" U joint center to center, the critical speed was anywhere from 5700rpm ,7800rpm, or 9200rpm. With you saying its 11295rpm is very reassuring. That means even up to de limited top speed of 215kmh it should be ok. . From my calculation ,11295...

between welds is 41.5", yes ratio is 4.56, tire diameter 25.5" tube OD 3", thickness should be 0.083". Do I need to grease the slip yoke splines ? Update, installed the prop shaft Overall, since the wall is thin, there is a bit of resonance when the car is starting up on high idle. I tested...

My mechanic suggested I go for a 1pc steel shaft. So he got one made. The new shaft feels like its half the weight of the OEM one with the bearing. The OE shaft front half OD is 60mm, and rear section OD is 82mm. The 1 pc is 75.15mm, in between both diameters. Here is the drawing I made. I...

I guess I am going to leave it for now, and not go tighter, the irony is the diff was rather quiet with toyota 85W-90 oil, I recently switched to amsoil 75W-110 and there is more noise. I am going to switch back to toyota 85W-90. In theory, it should be possible to get a proper preload with a...

Here are pics of how he secured the u joints.

Ok an update. I think everyone know about my propeller shaft rebuild. I just removed it and in the process I rechecked my pinion preload. It seems to still have preload but I also noticed that it has lost a little preload. There is a very slight hum especially when the diff "floats", meaning...

Unfortunately, the u joints were not swapped as per TSRM. you see, this so called pro removed the old U joint and replaced them with a compatible unit, without circlip cuts. So instead of securing with circlip, he put thick washers in the outside holes to "cap" the bearings, then welded the...

Indeed, I bought a beck arnley 75 Celcius and it was wildly inconsistent.

So most of you guys know my story last year, about my diff and steering centering. Well I finally settled my steering rack centering and got a full alignment and tire balancing and the car is going straight now. However, since I thought the car is ok now, I opened up the throttle and went up to...

In my experience with my previous car, aluminium radiators do not overcool. That being said, the stock radiator does its job well. I live in the tropics and the weather is always hot here. I have been stuck in traffic for long bouts of time, with the engine in idle (600 - 800rpm) with a slow...

Stock all original. My car has low miles.

I use Toyota Red, and mix at 60 water 40 coolant, because I live in the tropics, it's never winter over here.

More Updates There is a hum from 80 to 90kmh, but goes away over that speed, I went to 105kmh for a few seconds and its very quiet at that speed. For the most part, coasting decel is also quiet. There is some whine-hum when throttle is transitioning between accel and decel, when the ring and...
