suspension/chassis/drivetrain service

[petegangies]

Hi all, I did a quick search and checked the FAQ thread, and perhaps I've missed it.. but is there a thread or guide about maintenance pertaining to checking, greasing, retorquing the suspension/chassis/drivetrain components?

So far, all I have is greasing/lubricating the propellor shaft and checking the steering linake for from the FSM.

Lubricate all grease fittings:

• Sliding yoke
• U-joints
• Double–Cardan joint (moly grease)

What does everyone here do? I have so far, replaced my steering damper and swaybar mount bushes. One of my swaybar end links look like it might be on borrowed time too (one of the boots looks like it may be leaking grease). Is there any way to test these before going to the expense of replacing them? Car has only 151,000km on the odometer.

I want to ensure I check, tighten and lubricate all necessary steering, suspension and chassis components at determined intervals.

It looks like dad had some grease nipples tapped into the rear shock absorbers too. I am yet to attempt to pump any grease into those. It looks like he's been doing the front propellor shaft as I can see the excess grease has flown up onto parts of the underbody.

I'd been keep to hear if there is a list or thread that consolidates all of this into one area.

Many thanks,
Pete

Pete, the 80 doesn't require anything other than what's listed in the manual, but age has an effect on rubber components that isn't listed in the manual's service intervals. Remember, it was written for dealership service during the model's life. That's why the service intervals stop at 60,000 miles.

You're about at the service interval for replacing the sliding yoke seal on the propeller shaft. Overfilling the yoke can cause this seal to fail. If you repalce it, don't fill it until after you install the shaft, or you won't get it in (the grease will cause the yoke slide outward).

Grease nipples in the shocks are a new one for me. They're gas filled at the factory; I don't know how you get grease in them without purging the oil and then I'm not sure how you'd know you have the right amount in the tube, if that would even work.

They are aftermarket shocks from a company here called Pedders! I'll send some pics over the weekend!

Steering gearbox oil? I doubt this has ever been done..

Is this for power steering models? Can't find any reference to that in my FSM.

• Sliding yoke
• U-joints
• Double–Cardan joint (moly grease)

For the sliding yokes ive always used castrol LMM moly - i'd recommend removing the shafts and cleaning all of the old grease from the internals of the slip joint if you do not know what has been used previously (be sure to mark the splines with paint before separating). My reason for cleaning the old stuff is some greases do not mix and can harden up and cause excessive binding

U-joints - ive always used Castrol HTB

I use 2 grease guns for this as its more convenient rather than swapping over etc and making a mess

Double - cardan - mine doesnt have one - are you sure yours has one as the image posted shows wishbone suspension parts at the front?

I'm not sure no. Need to have a proper look over the weekend!

Hi again, I'm thinking of replacing my current shocks and springs, they've been on the vehicle since 2007 and have done approx 50,000kms. They are standard height coils and foam cell shocks, from an Australian brand called Pedders. Car is running on BF KM2 Mud Terrains (manufactured in 2013) in 285/75R16 and the ride comfort can best be described as "bone jarring". It rides horribly and you feel every bump in the road. I know the muddies are probably contributing quite a bit to the harshness, but I suspect the Pedders suspension will be too. The car tows are relatively small boat and has a dual battery setup in the engine bay. I've seen a lot of people here run the factory Tokico shocks and OME 861/862 coils, which results in a compliant and comfortable ride. I don't do any hardcore offroading. The tyres will be replaced with Yokohama Geolandar G018 ATs, so will be much better on the road.

I have a 1994 FZJ80 landcruiser. I see quite a few different part numbers for shocks. Availability is the issue. I can however, get my hands on the following:

• Toyota Genuine Parts Shock Absorber ASSY RR LH Land Cruiser VAN Part Number 48531-69416 and
• Toyota Genuine Parts Shock Absorber ASSY FR LH Land Cruiser VAN Part Number 48511-69385

Would these fit my vehicle?

Failing that, I have access to Bilstein B6 shocks here and probably can get the Dobinsons Stock Height Restoration IMS Kit for 1990-97 Toyota Land Cruiser 80 Series - DSSKITIMS2 kit.

Thanks,
Pete

You were right of course.. the nipples I was thinking of, were off my inverted Subaru STI shocks back on my old 2002 WRX STI. They used to suffer from "stiction" and would stick and drop at the lights. Pumping some grease into them had them working correctly again and would last around 10,000km each time before needing to be done again. The reason I got them confused with the Landcruiser, is because both the struts are red in colour.
