Posted: Tue Apr 23, 2019 13:31 Post subject: Seeking advice on Shock absorbers and leaf spring bushes |
|
|
I have decided to do some work on the the suspension, I have been to a Mitsubishi dealer and the they are saying it will take 56 days to get shocks and bushes to match my vin number.
I would appreciate some advice, where can I find compatible shocks and bushes to fit a JB 500.
Any help greatly appreciated.

Hi there!
This is an L300 given the forum section this is in? I'm not sure what JB 500 means...
This thread may help:
http://www.MDOCUK.co.uk/forums/viewtopic.php?t=48197
KYB Gas Shock Absorber
Part numbers 344111 (front) and 343226 (rear). Several online places sell them, including "that auction site" (where I bought them, two years ago, and they are still going strong).
I would suggest using a different garage, given that advice...
Cheers

A JB 500 is an after-market Coachbuilt motorhome, on a 4WD L300 Chassis.
The JB 500 style is duplicated on the 1992 Mazda Brawny 4x4 chassis.
There is also a JB470, which has a windowless front end on the overcab section. It is built on a L300 Express P25T chassis.
If you want to go a bit beefier, with more overland capability and ground clearance, then checkout a 1992 Izuzu Elf:-

Thank you jejoenje i will check these out. but this makes me think of another question, The L300 with JB500 body is heavier than the normal L300 van, would this made any difference to which shocks I choose, plus I spend a fair amount of time off road wild camping, would these be suitable for off road,

Ah I see.
I have no idea what the sort of limits to those shocks are on terms of weight.
As to off road... I've been off road with them... not sure if that helps you much though.
Google around those part no's and more widely on this forum, there are plenty of recommendations, including for ones from well known and respectable off road manufacturers. _________________ 1992 L300 Exceed "Selma" |

The L300 chassis cab was the platform for a wide range of body types, mainly available only in the far east. ( I remember seeing a 4WD tipper designated Delica in Sri Lanka 3 years ago). These have continued to be manufactured in the Philippines until very recently, especially as a box-bodied taxi-bus, and using the straight window (old style)cab. Some googling may provide results. Alternatively, if you can give the dimensional and mounting specs/eye-bush sizes, shock absorber specialists may well be able to help you, in fact they may have have your JB500's specs on file. Good luck, they are well worth the effort. _________________ Andy C L300 Super Exceed - over 100 smiles per gallon! |

Landranger,
I have a JB470 on a 1999 P25T 4WD chassis cab with only about 25000 miles on it.
I have now changed all the suspension, but start with saying mine may be a (bit) lighter than yours.
Its a GVW of 2560Kg (Kerb 2230Kg, Front 1040, rear 1190).
Front OE shocks were MR113437, I have now fitted KYB Gas-a- Just KYB554103 from a 2.5 4WD L400 Delica.
Rear OE shocks were min length 320mm, max length 630mm. I struggled to find matching ones, but went with KYB553222 Gas-a-Just from an L200 (pre 2005).
These are a bit tight on minimum length, but I have raised the ride height by about 1" so they are okay. I found fully loaded I used to be only 1" off the rear bump stops.
Rear springs (Axle-over-spring config) - I have changed the OE 4+1 leaf for some HD 5+1 Jones springs from a 2007 - 2015 L200. Fitting these required a slight mod to the front hangers to suit the L200 spring bush. The springs also needed a re-assembly to suit the L300 shackle plate config.
These give me the extra 1" ride height, but on reflection should probably gone for the extra HD 6+1 springs to reduce some of the body roll. (Does yours roll a lot when in cross winds??)
I also need to rebush the steering relay (Bellcrank), as its got a bit of play in it. The steering box system is totally unlike the rest of the L300's!!
Hope this helps, as this took me over a year to find all the information!!
If yours in not a P25T 4WD type, then this info may not help......
PS - the guy at viamoto.uk is exceptionally helpful.
Dave. |

Hi dave thank you for your advice,
I will certainly check out the shocks that you have mentioned. I have found a place in West Bromwich that will make new springs, so I have decided to go for it. the only problem is the bushes, they are not sure they would have bushes to fit.
Yes mine does roll a lot in a cross wind.
Could please tell where did you you find your GVW. |

The OE bushes are purely rubber halves - see this diagram for part numbers.
https://www.megazip.net/zapchasti-dlya-avtomobilej/mitsubishi/Delica-truck-9340/p25t-19951/yhnjt-624469/rear-susp-7918774
When I looked, they were easily obtainable.
The rear bush on my new L200 spring fitted fine to the existing shackle pin.
I had to buy new L200 spring bolts to use the front fixed bush that came pressed into my L200 spring, and modify my front spring hanger to suit.
My GVW and axle weights were on the Japanese export certificate - if you haven't got one, it may be hard to find out, although I know someone with an older JB500 who was quoted the same weights as mine, which is probably not surprising, being the same base chassis cab.
Glad yours rolls a bit as well, as mine is a bit disconcerting at winds above 20 - 30 mph!
Would be great to compare notes!
Cheers,
Dave. |

Thanks dave
Motorway buffeting is one reason i tend to drive via A and B and and local roads, and of course the beautiful country side is the seconnd.

Ps any ideas on avoiding brake fade and increasing breaking efficiency. I have normal discs up front and drums at the rear. |

I don't have any problems with my brakes - but they have the original manufacturers pads, maybe yours has some cheap pads fitted?
Mine is also a manual, so I use the gears on steep downhills.
My last MOT commented on the lack of rear brake efficiency when on the rollers, but there is a load sensing valve at the back, which should come into play when braking hard and the front dips.
Like you have found out, you have to drive it with respect, and never forget we have a large narrow brick with a fairly high centre of gravity!
Definately one for A,B and unclassified roads - there are no roads I wouldn't take it on, unlike 'lesser' motorhomes...
