    1PZ Timing doubts...

    Hi, I was just about ready to put the covers back on the engine having completed the timing belt, timing belt idler, spring, camshaft seal and water pump replacements and noticed that the timing marks between the crankshaft pulley and camshaft pulleys 1 & 2 were off. Both camshaft pulleys 1 & 2...

    Hi, In the process of changing the timing belt, water pump + belt as well as A/C belt, thermostat and camshaft oil seal on 1PZ and just noticed what looks like very fine cracks or casting marks on both sides of the oil seal retainer. Also there appears to be a slight lump on the back side at...

    PZJ77 replacement fuel tank

    Hi there, I've had a small leak under the tank for the last month or so and finally decided to empty the tank, remove the straps and shield to have a look underneath. Overall the tank is in pretty good condition but in one area where mud/water has accumulated between the rubber pads and the...

    Toyota knuckle centering tool variants

    Hi, I've read somewhere on this forum that the Toyota SST used for centering knuckles was a universal fit between LC series and that it was just a matter of using the supplied adapter bushing or not depending on the axle you have. I don't know if this is true or not. I've just purchased the...

    Correct rear axle bearing for 1991 PZJ77-MNS

    Hi, Can anyone confirm these are the correct bearings for the rear axle on a 1991 PZJ77-MNS? 2 x 90365-47013 Partsouq also gives a Koyo equivalent as being RNU0727 but they don't stock it at the moment. This is a semi floating axle so am I correct in thinking that I should also expect to have...

    Shaft resting position inside spindle

    Hi, I completed a knuckle rebuild about a month ago on my '91 PZJ77 along with changing all the bearings and seals in both knuckles and hubs. I just finished a 10,000km trip and during the last 1000km or so I had a light grinding noise accompanied by a high pitched squeal between 40km/h and...

    Stripped knuckle threads...

    Hi, While reassembling knuckles following a full front-end rebuild I just noticed that 6 of the 8 threaded holes on the face of the RH knuckle are stripped. I'm guessing someone used an impact driver instead of a torque wrench... If I can't find a replacement part quick enough I'm considering...

    PZJ77 LX suspension seat graft

    Hi, I'm considering replacing the current stock fixed seats in my 1991 PZJ77 LX. The first step would be to graft the suspension bases from a 1991 HZJ77 ZX and I would like to know if anyone has done this here? I don't currently have the bases at hand to measure and compare but exchanging pics...

    Hi, The truck is running fine, no over heating, no leaks around the radiator either. Just a bit of rust and these ugly fins sticking out at the bottom (some appear to have been pushed in as well). Have been putting them back in place once in a while but since I have most of the front of the...

    Sudden steering swaying

    Hi there, I've been having an issue since last spring on my 91' RHD PZJ77 which has been getting progressively worse. When the front left wheel reaches the center of the road or when I'm driving on roads with deep ruts the truck will suddenly sway to one side or the other. I can't feel any play...

    1991 PZJ77 A/C question

    Hi, Wondering how I can tell if the refrigerant in my truck's A/C has been changed to 134A or if it still uses the original R12. My understanding is that the connectors and the drier would have been changed if that was the case but it looks like the A/C pump still has the original R12...

    Steering damper stud thread

    Hi there, Have just finished changing tie rod ends on a 1991 PZJ77 and I've lost the nut that goes on the stud that links the steering damper to the relay rod. Can anyone confirm what the thread is on these? All I have to verify the thread is a metric tap&die set and it looks like it could be...

    Lighting modifications, trailer harness and power outlet...

    Hi, Just received a 1991 PZJ77 and I'm in the process of making a few modifications to the exterior lights in order to pass inspection. I intend to convert the two white lights located under the front flashers into DRLs and add a required third brake light somewhere above the spare wheel. I've...

    70 series HV and V suffix meaning

    Hi there! While perusing 77 models on the JDM auctions I've noticed that both the HZJ77 and the PZJ77 can have V or HV affixed after their model number. On this forum they make the following distinction : HV = Japanese market ordinary truck, hard top V = Japanese market light truck, hard top...
