Mr ZN; I meant you pioneered the wearing out of bearings by adding too much tension - was that you?

LOL

[zukenutter]

Yeah that was me. Brought about through the wobble persisting every few weeks. I had the swivel hubs pretty stiff, was really nice to drive though... until bearing collapse

[Paulw]

My Jimny is wobbling more than Gina Rhienhart's ass at the moment since raising the front another 15mm and fitting the 29.1' tyres, I'm hoping the set of JB front arms will rectify it but I've also got a set of the bigjimny shims just in case.

[Jezza86]

jb arms are great at 3"
wouldn't want any less but. recomend a 1/2" prop spacer. front axle do sent have much meat on the splines otherwise

[Paulw]

Thanks Jezza have been trying to figure out which size spacer to buy.

[zukenutter]

I don't run a spacer on my front shaft, silver or black Jimny. The shaft almost follows the same path as the control arms, so I don't think there's a lot of travel in the yoke anyway. Paul, I'd suggest that you fit it all up and then decide what size spacer, if any.

[Jezza86]

zn still running 4" lift?

[zukenutter]

Yep, until I wear out the 30s, then I'll run 235s and 80mm

[dawoode]

Jezza/ZN , can I take the panhard rod off while the car is just stood on the driveway. Or do I need to jack it up at all? Just starting to do my own work so my questions may be quite novice ones... the reason is so i can replace the panhard bushes with superpro poly's...

[zukenutter]

Yes you can. If the eyes don't line up when you are bolting it back in, use a ratchet strap from chassis to axle to pull it into position.

[Jezza86]

assuming your bushes are not completely gone in your front arms, and your not running these crazy bearings for bushes ZN just put in the ebay thread yes. (LOL great find ZN)

from memory the panhard is a 17mm head on the bolt. you want it to be as tight as possible doing it back up (after checking those bushes). if you can break the bolt without an extension then the bolt wasnt strong enough.

if either of these bolts fall out, you will have no steering, and will be lucky to not die if your going fast round a corner when the bolt lets go.

Are you lot replacing the rubber scraper seals as well? Bearing preload is about the bearing running in its proper conditions so it doesn't wear early.

Yeah this does seem to have been neglected along the way, although the Jimny scrapers don't seem to add much in the way of resistance compared to the felt version in a Sierra

[Jezza86]

from what ive seen scraper seals add ~.1-.2 kg at most, so set the preeload to 4.5kg with the scraper seals on and your actually at 4.2-4.3kg. which has been enough to stop all my wobbles, andive never crushed a bearing even driving on these tracks.

[dawoode]

AZ CREW/STAFF, do you know any where else to get some King Pin Shims besides Big Jimny & Jimny Bits, they are all out of stock. Or can you confirm the size & I'll get some made up? I believe they are 25mmOD 15mmID?

[Jezza86]

Suzuki sell them. Costs cents.
0.2 mm, 0.5 mm are the widths youll want to be playing with.
Pin hole is 15mm
shim is 22mm in diameter but reckon you could push it to 22.5 or 23mm diameter and it will still be a good fit

Or the previous owner read somewhere about adding shims but didn't do enough research, went to a dealer, asked for shims, and they sold him a set of Sierra KP shims thinking that was what he wanted. I've never heard of the Sierra style shims being used on a Jimny and it's not mentioned in my workshop manual.

They aren't shown on the parts database either

[dawoode]

My local suzuki dealer is aware of the problem and have done many jimny's. They have ordered all the parts for me at trade price (king pin bearings & shims) & have offered to do all labour at trade price, as long as I have the original tyres and rims on the vehicle when it comes in. They have strongly advised because of the km's on my vehicle (95,000km) that I should think about replacing the 3 seals in the scraper seal assembly & have it all serviced and regreased. Does this sound about right?

[zukenutter]

worth doing while it's apart

[Jezza86]

i would be getting the hub rebuilt. bearings, all the seals, all at once.

[dawoode]

New Pan Hard Bushes installed.... Shims added by Suzuki dealer and tested preload... They checked the amount of meat left on the dics's aswell (all good).. All recommended by Suzuki Bulletin from Japan... New king pin bearings added aswell... Redone all the scraper seals and regreased with the graphite grease stuff...

It feels ok for the drive home.. Next morning gave it the test by feathering the brakes at 80km/h slowling down at a real easy pace.. Surely enough the wheel starts to wobble and then continues till the whole front end of the car joins in... Have to pull over to make it stop....

$780 later... The problem is still there.... I am really hating my Jimny at the mo....

[watermouse]

Was that still with the stock tyres on or had you changed back to the AT's when the wobbles started again?
How does the offset of the new rims compare with the stock rims?

[dawoode]

That was with the stock wheels and tyres on it.. I haven't bothered trying the big set as it's a certainty that it will wobble with them..

[zukenutter]

Have the stock wheels and tyres been balanced amongst all the other work?

[Jezza86]

do you have an adjustable panhard? did they rattle gun on the panhard bolts, or actually torque them up to 170N

[watermouse]

Tyre balance is worth checking but to me it looks like it could be a result of the lift.

I suggested a while back to check the castor correction bushes are installed the right way. (You may have done this) Find out what the stock castor angle is and try to match that. If the king pin angle is any more vertical after the lift than stock then this reduces the stability margin of the steering system. (if jimnys ever were within it )

You may need aftermarket front trailing arms that correct for a bigger lift but look at that later.

Did you get a wheel alignment after the lift?

Also have a closer look at your brakes. You say that the discs were measured. Was that for wavyness or just adequate thickness?
My Jimny had shuddery brakes at all speeds and before I did the knuckle overhaul it could set up the wobble at faster speeds, particularly downhill.
I changed the discs and pads but while doing that I also found the drivers side calliper had a seized sliding bolt. This meant that the inner pad was contacting but it couldn't pull the outer pad to the disc properly, flexing the disc slightly and twisting the calliper when applying brake.
This is less likely after your service but would be worth checking that also.

[dawoode]

I havent balanced the wheels since getting it done. He was checking the brakes for thickness of the disc as advised by suzuki japan bulletin. The panhard is original with superpro bushes just added, I'd only be gussing that they were torque set and not rattled on.

I spoke with suzuki again yesterday and the workshop foreman says they only put a shim on the top of each side at 0.5mm supplied by suzuki japan through the bulletin, then set preload to 4.6kg. I asked him what woul happen if he put too much preload on the bearing, would it crush the bearing prematurely.. He said no, it would just hinder it returning to centre...( obviously a mechanic and not an engineer)... He then explained the rear bushing on the radius arms have had an upgrade by suzuki and are to go hand in hand with fixing this problem, so he would like to replace them for me. $30 each side.

After this he told me because of the lift there is no way this wont stop happenning and that I would have no warranty for the work they had just done unless i return it to normal ride height.. Iam going to return it to normal height while it's my daily driver for the next few years.. Once I get a new daily driver to work and back then the girl will be lifted abused and a dedicated scrubber....

[watermouse]

case closed...

[Gwagensteve]

Until next week when someone suggests fitting a steering damper to "cure" the wobbles.

[dawoode]

Lol... has already been suggested...
