bearing repacking

[jkyamog]

Saan po ba ang JP Wheel sa paranaque? Ang presidents ave ba yung road from Tahanan papuntang Mcdo? Mayroon ba dito alam tel number ng JP Wheels? (Hindi kasi puwede JP sa search, too short daw, dami naman kapag wheels) Thanks.

jkyamog::: Dipende sa differentials kung live axles or semi-live axles ang rear differentials. I would suppose your sample has rear brake drums. You will have to remove all brake parts, brake shoes & springs, in order to pull out the axle, there should be 4 bolts mounting it from back plate. Remove bolts and back plate. You should be able to see the axle and oil seal. Pull out the oil seal carefully to avoid damage and may be reused if not damaged in the process. Some have cone & cup type bearings that have solid axle bearing locks which will need to be pressed out in a machine shop. While other axles have twin cone/cup/cone type.

Now for the front 4WD IFS, you will also need to remove brake pads, raise caliper, remove front hubs to be able to pull out the front axles. Yes, axles boots can also be replaced in the process, brake rotors skimmed, pads cleaned or replace. Ball joints and tie rod ends are optional. Another important part to clean or replace if needed are oil seals.

Ungas: Meron ako nakita dito sa bahay na American Brand Lithium Moly Grease.. pwede na ba ito? Ito ang gamit ko sa CV joint ng ESI ko dati.

[jkyamog]

Ungas thanks very much for the good explanation. I will add oil seals in my fix. Now only problem is that its a Feroza I just hope a toyota axle boot and oil seal is available. After my Feroza next naman ang Terrano. Very similar drivetrain.

My choices to service are: Minerva, I ask them na, ok naman ata labor 400 each. Any feedback sa Minerva sa alabang area? Servitek either yung sa alabang or sucat, I heard some negative feedbacks na sa servitek alabang. Dati doon ako nagpapagawa ok naman, dala lang ako sarili parts. JP Wheels, but I don't know where they are. It seems highly recommended sila. I just wish someone can give me a number or direction to go there.

I am glad to learn this new things, para naman pay back time ko na sa feroza ko. Super bait sa akin walang tirik problema, etc. 200Kms++ na ata, ngayon lang matatikim ng bearing repacking.

I looked at google and read what is a live axle, I think a feroza rear is a live axle. I have another question. Is pressing the bearing out always a needed step? So I know if I need to ask the mechanic to do this. Is it supposed to be always done by a machine shop? Para lang malaman ko if the mechanic is trying to force things.

[OTEP]

Parang mahal ang 400 each. Php 250 lang kina Chieffy dati.

Try mo kaya kay Speedyfix sa Pasong Tamo. PM mo na lang siya. Poster yun dito.

[jkyamog]

Hi Otep,

Sa pasong tamo lang ba sila speedfix hindi ba sa Shaw? I have texted speedfix and asked for quotes. Pricing is normally competitive and he seems to have a very good reputation. Problem lang kasi sa akin is I live in las pinas. Malalayo kila speedfix, although kung pasong tamo lang iyan its much better.

So I normally ended up paying for more or doing the job in a less reputable place. Wala bang speedfix alabang

mdpo::: Sound good to me, but better check the details if it is used for high speed. High temp is optional but worth the spec.

jkyamog::: Feroza uses same platfrom from Toyota Blizzard. So you can be sure that there are parts that can fit perfectly. About the machine shop procedure and steps in pressing out the cup or lock. Kailangan nyo na bumili ng bago, once this piece of metal is pressed in and out or vice versa. Nawawala na yung integrity nito, ang probably misconfigured in the process. Kadalasan press out by machine then pukpok sabay bagsak ng buong axle sa semento. Just ask them to do it more carefully, minsan nabibingot ang axle splines in the process of dropping it hard on to the ground. Kung ayaw nyo ng bagsak style, acethylene ang paraan, tutunawin yung lock para lang matanggal. Heating metal is not good also. (Eto ginagawa sa L200 4x2 axles)

YAAAAAAAAAIKS

ang dami palang kakalisin sa bearing repacking

mukhang nakaktakot...uhuhu sana safe nalang to

[mdpo]

Ungas: Found in the internet .. this is the grease I am mentioning.. pwede na kaya? Di sya hi-temp.

American Grease Super Moly Lithium Grease

A Lithium soap based grease with consistency grade NLGI No. 2. It is a good quality molybdenum disulfide compounded multi-purpose grease also treated with soluble chemical additives to prevent wear especially under very highly loaded conditions. Uses in general purpose applications where medium to severe conditions prevails.

[jkyamog]

Ungas,

Yes its a Blizzard, sana there where Blizzards sold locally. Or sana dumami ang subic na Blizzard, or sana they start importing Japan Feroza

Just one clarification. When repacking the rear bearings, does it always have to involve pushing out the bearings (which also means machine shop involvement)? If it does I should also prepare to buy bearings to replace them, since from what I understand based from your explanation once its been pushed out by the machine shope i can't be put back in.

[Ungas]

mdpo::: You will need some more tech specs as to viscosity and temp range. Check out this page to view as sample only: click here! We normally recommend LGMT 2 & LGMT 3 for our grease line up. If you want a more suited high speed and high temp grease, a lower viscosity LGHP 2 would definitely fit in. HTH

jkyamog::: Dipende po sa uri ng axle bearing na gamit nyo. Meron kasi axle bearings na pwede i-repack ng grease yung cone without having to press out the cup or lock. Meron din kasing axles na hindi mabubunot ang cone bearing without pressing out the lock first. You will only need to buy replacement lock for the bearings if it will be pressed out, kung hindi pa malaki ang gap ng cone/cup bearing, repacking should save you money. Don't be alarmed when you see tarnished colored metals, karaniwan na po ito sa bearings na kadalasan nalulublob sa baha habang mainit pa or natutuyuan ng grasa. Yes, once the lock is pressed out by force, lumuluwag na ito and it doesn't serve its purpose. Sasabihin ng mga mekaniko pwede pa kung may konting bingot sa ridges. We don't recommend it though, just to be safe. Mahirap mabunutan ng axle sa byahe.

Thanks Ungas

Valuable info that should help me maintain my 2 old cars.

[mdpo]

Ungas: medyo nahilo ata ako dun sa oil specs ah! hehe tiningnan ko yung lalagyan wala ako makitang specs or grade eh.. panu ba ito? Can you just recommend something good that you personally use for bearing repacking.

thanks.

[Ungas]

mdpo::: To save you the hassle of thinking what's best for your daily city driven ride, the brand you posted Liqui Moly grease should be fine. :D

[mdpo]

hehe ok thanks!

Hello Ungas,

I went to Felson today since they are the shop that I buy my daihatsu parts. They are pretty familiar with it. I got my bearings and some other parts. For my bearing repack for the rear axle, I got 2 pcs oil seal, 2 pcs lock (looks like a big ring), 2 pcs bearing (bigger ring).

I have question. They gave me 2 different brands since they could not get the same one. One is NTN, another is Koyo. Both have the same outer and inner circumference but have different ring thickness. So the rubber circle area is different from the two. Common sense say that they should be the same since the only important thing is the outer and inner circumference right? Please kindly verify. Also are those good enough brands?

Since I have already the lock and oil seals, is it still advisable not to change the bearing. I just regrease the original bearing and put the new lock and oil seal? I keep the new bearings just in case the original breaks in the future. I am just thinking about this since the old one are genuine parts and there is nothing really wrong with it, I keep using it. Or in your opinion I replace the working genuine bearing with the new replacement bearing?

[Ungas]

Bearing width or thickness measurement can be vital if the shaft and workspace is limited to what it used to have, but since we are dealing with lockable shaft axles, pressing the lock back into place will be its crucial point.

Try to test the OE bearings if the cylinder rollers are still intact and rolls smoothly. They should have ~0.5mm tolerance for the grease to move around them. Or you could simply compare the Koyo brand to your existing ones, if it rolls almost the same without excessive misalignment or vibration then it should be fine.

Imo, try to find the same width with the other pack, it will be easier task for your mechanic to work on. NTN is a good and cheaper alternative, but only Koyo brand passes when it comes to quality controls.

[jkyamog]

Thanks for the great added info. Actually they are the same in size. Basically the donut are the same size, the difference is the icing (rubber) in between the rings. Koyo has thicker rings so the rubber is smaller as compared to NTN, which has thicker rubber and slimmer rings. I will try to see if I can ask Felson to replace the ntn bearing with another Koyo.

[Ungas]

Are we tackling Diahatsu Feroza rear bearing? For your reference, I've checked on our list: KOY.DG 358021 WYAC4

Rubber shields are just covers, I'd vouch for thicker rings, so that the roller balls will not be dismounted from heavy usage.

Check PM.

[jkyamog]

Yes its a Daihatsu Feroza. Thanks for the info Ungas, very useful. I have replied to your PM. Ok lang i-post ang prices dito for reference.

Sa mga may Feroza:

Bearing 380
Lock 250
Oil Seal 85

I got it sa Felson (pasay Rotonda) since they are familiar with Daihatsu. Look for Henry tell them refered po kayo ni Jun Yamog. Tel 8323547, 8333302, 8339231.

I will post sa DCP boards more details after ko mapagawa na.
