Breaking-in axle components

After rebuilding the entire axle assembly, it was time to break the components in. I wanted to do this effectively – so after reviewing some existing knowledge and checking if they still held up against any new material, I documented the details here in case it’s helpful for anyone. Most, if not all have probably […]

Bearings & New Sump

My 4AG engine developed more noise around the rear – towards the end of the exhaust cam. The 4th cylinder was also noticeably hotter… Further investigation revealed the 4th runner was always discolouring first: Initial thoughts were a bent camshaft and/or worn connector rod bearings (4th cylinder). Seeing that the bearings were overdue for an […]

NEW TUNE TEST DRIVE

After 2-3 days of constantly checking my work and making final adjustments, I was able to inch out for a test drive. Butt was clenched the entire time… There were a number of things to monitor – too many… from brakes all the way through to engine, driveline, suspension and diff… As they checked off, […]

トヨタ 4.778 + CUSCO RS (pt.2)

After driving the oil seals into the axle housing, I focused my attention back to the centre. This is where the pumpkin goes back into the housing 🙂 While inspecting the region, I soon realised I forgot to replace the factory mounting bolts before putting the housing back onto the chassis… Though most were fine, […]

トヨタ 4.778 + CUSCO RS (pt.1)

After contacting Sam at Neat Gearboxes, I eventually took the OEM route and got my LSD assembled with a Toyota 4.778 ring & pinion. I eventually restored my original zenki axle housing, along with new hard lines ready to house the new setup. This followed with all the parts being removed from the kouki axle […]

Rear axle rebuild 2

Yep… this time round, my zenki differential gets the treatment it deserves… Using a slide-hammer, my axles started to come out slowly: Here’s a picture of it gaining some distance away from the housing, you can see the bearing surface peering through: Eventually it gave way and came out… the bearings were surprisingly in good […]

4AG Breathing Work

Picked up my cylinder head back from the shop 🙂 Several years of carbon build-up now gone, I was more than happy to torque it down with a new gasket: Having the opportunity to replace all the seals finally came. Over the past years I only upgraded the head with lighter internals and didn’t do […]

Braking System – Rear

In a previous post, I did an overhaul of my front hubs and brakes. The rears had to wait until the axle was put back into the chassis. Now I finally managed to get the rear brakes in 🙂 New rotors – along with rebuilt rear calipers: Just like the fronts, new brake pads went […]

Braking System – Front

When I raised my car, I noticed the front hubs were not moving as smoothly. There was a fair bit of resistance and inconsistencies could be felt by hand. After prying things open to check, I realised the bearings were on their way… Front bearing install The front hubs were taken out and ready to […]
